Claim 5 · True· Confidence: High
"QRO: ~2.4 million passengers in 2025 with around 9 US destinations (Dallas, Houston, Chicago, Detroit, Atlanta, San Antonio, Denver, LA, Orlando) plus a Madrid route... SLP moved ~835,000 passengers with 3 US routes (Dallas, Houston, San Antonio)"
Querétaro's Intercontinental Airport closed 2025 with 2,426,000 passengers (+16% YoY) — matching "~2.4M." Its US route list (Volaris' 11 new routes plus existing Aeroméxico/American/United service) covers exactly the 9 cities named, plus the Madrid route that launched December 2025. San Luis Potosí's Ponciano Arriaga airport closed 2025 with 834,795 passengers (+13.4% YoY from 736,000 in 2024) — matching "~835,000" almost exactly — with the Houston/Dallas/San Antonio routes launched July 4, 2025.

CONAGUA's official disponibilidad media anual (DMA) determination for the Valle de Querétaro aquifer states a deficit of -63.724840 hm³/year (extraction 129.7 hm³ vs. recharge 70.0 hm³) — an exact match to the article's cited figure. Independently, more than 300 colonias in Querétaro were reported without water service in early September 2025 due to the Zimapán dam discharge suspending Acueducto II, with the state water commission (CEA) implementing tandeo (rationed rotation).
3 sources cited
Claim 9 · True· Confidence: High

"Unemployment 2.2% vs 3.0%; informality 39.0% vs 55.7% (INEGI Q1 2026) — the informality gap is the real story" [Querétaro vs. SLP]"
INEGI's ENOE bulletins for Q1 2026 confirm, at the state level: Querétaro unemployment 2.2% and labor-informality rate 39.0%; San Luis Potosí unemployment 3.0% and labor-informality rate 55.7% — an exact four-for-four match to the article.
4 sources cited
Claim 12 · Partially True· Confidence: Medium
"Querétaro's metro added over half a million people in a decade (+39.5% by the official 2020 count — Mexico's 2nd-fastest-growing state)"
Directionally and in order of magnitude the claim is correct — Querétaro was Mexico's 2nd-fastest-growing state by annual rate in the 2010–2020 census decade (behind Quintana Roo) — but the precise "+39.5%" figure could not be independently reproduced. Using INEGI's most commonly cited five-municipality metro-zone delimitation (Querétaro, El Marqués, Corregidora, Huimilpan + Apaseo el Alto, Guanajuato), the calculated growth from 1,161,458 (2010) to 1,594,212 (2020) is 37.3%, not 39.5%. A separate real-estate industry analysis (4S Real Estate) cites "~40%," while a UN-Habitat citation puts metro growth at 48% — all in the same neighborhood but none matching 39.5% exactly.

Investigation summary

Directionally and in order of magnitude the claim is correct — Querétaro was Mexico's 2nd-fastest-growing state by annual rate in the 2010–2020 census decade (behind Quintana Roo) — but the precise "+39.5%" figure could not be independently reproduced. Using INEGI's most commonly cited five-municipality metro-zone delimitation (Querétaro, El Marqués, Corregidora, Huimilpan + Apaseo el Alto, Guanajuato), the calculated growth from 1,161,458 (2010) to 1,594,212 (2020) is 37.3%, not 39.5%. A separate real-estate industry analysis (4S Real Estate) cites "~40%," while a UN-Habitat citation puts metro growth at 48% — all in the same neighborhood but none matching 39.5% exactly.

Fact-Check Investigation Report: San Luis Potosí vs Querétaro: Which Is Better for Expats? (2026)

**Source Analyzed:** https://www.sanluisway.com/blog/san-luis-potosi-vs-queretaro-expats-2026

**Verification Date:** July 2, 2026

**Investigation Conducted By:** San Luis Way Fact-Check Team using AI-powered research agents

EXECUTIVE SUMMARY

**Total Claims Analyzed** | 12

**Overall Reliability Score:** 9.3/10

**Confidence Level:** High — Nearly every figure in the article was traceable to a specific primary source (INEGI/ENOE, INEGI/ENSU, CONAGUA, FUNSALUD/Blutitude, Numbeo, Expatistan, OMA airport traffic data, BMW Group press) and matched to within rounding. The article's internal note ("Dossier cautions applied") is borne out — this is one of the most rigorously sourced posts we've reviewed in this series. The single partial-true finding concerns a metro-population growth percentage that is directionally correct but not independently reproducible to the exact decimal cited.

DETAILED FINDINGS

CLAIM 1: Safety Perception Gap (ENSU March 2026)

**CLAIM:** "In INEGI's March 2026 survey only 35.3% of Querétaro residents feel unsafe vs 57.6% in SLP"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** INEGI's Encuesta Nacional de Seguridad Pública Urbana (ENSU) for March 2026 (first quarter 2026 cut) shows San Luis Potosí's insecurity perception at exactly 57.6% — an exact match. Querétaro capital's security-perception figure was reported at 64.5% (implying 35.5% feel unsafe), a 0.2-point rounding difference from the article's cited 35.3%.

**EVIDENCE CHAIN:**

**Primary Source:** [INEGI ENSU boletín, March 2026](https://www.inegi.org.mx/contenidos/saladeprensa/boletines/2026/ensu/ENSU2026_04_RR.pdf) — national urban insecurity perception data
**Corroborating Source 1:** [Líder Empresarial — Baja 6.4% la inseguridad en San Luis Potosí al arranque de 2026](https://www.liderempresarial.com/baja-6-4-la-inseguridad-en-san-luis-potosi-al-arranque-de-2026-ensu/) — confirms SLP at 57.6%
**Corroborating Source 2:** [Rotativo — Querétaro capital escala 12 lugares en percepción de seguridad](https://rotativo.com.mx/queretaro-capital-12-lugares-percepcion-seguridad-ensu-inegi) — 64.5% security perception, 14th of 91 cities
**Corroborating Source 3:** [Amanecer Querétaro — Percepción de seguridad en Querétaro sube a 64.5%](https://amanecerqro.com/percepcion-de-seguridad-en-queretaro-sube-a-64-5-ensu/)

**DETAILED ANALYSIS:** INEGI reports "percepción de seguridad" (safety) for some cities and "percepción de inseguridad" directly for others in its press materials; both are the same underlying question. Reverse-computing Querétaro's insecurity share from the security figure yields 35.5%, essentially identical to the article's 35.3% within normal rounding/report-vintage variance. SLP's number is an exact match.

**CONFIDENCE:** High — SLP figure is an exact primary-source match; QRO figure matches within 0.2 points.

CLAIM 2: Overall Cost-of-Living Gap

**CLAIM:** "San Luis Potosí is about 8% cheaper overall (Expatistan, May 2026)"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** Expatistan's live city-comparison page states San Luis Potosí is 8% cheaper than Querétaro, current as of May 28, 2026 — an exact match to the article's figure and cited source.

**EVIDENCE CHAIN:**

**Primary Source:** [Expatistan — San Luis Potosí vs Querétaro cost of living comparison](https://www.expatistan.com/cost-of-living/comparison/queretaro/san-luis-potosi) — "San Luis Potosí is 8% cheaper than Queretaro. May 2026 Cost of Living."

CLAIM 3: Monthly Rent, 1BR/3BR City Center

**CLAIM:** "A 1BR in the center averages MX$11,800 in SLP vs MX$15,563 in Querétaro" (and MX$21,333 vs MX$27,125 for 3BR)

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** Numbeo's live pages (fetched directly, June 2026 data) show San Luis Potosí at MX$11,800/MX$21,333.33 and Querétaro at MX$15,562.50/MX$27,125 for 1BR/3BR center rents — exact matches to the article's figures (MX$15,562.50 rounds to the article's MX$15,563).

**EVIDENCE CHAIN:**

**Primary Source:** [Numbeo — Cost of Living in San Luis Potosi](https://www.numbeo.com/cost-of-living/in/San-Luis-Potosi) — 1BR center Mex$11,800; 3BR center Mex$21,333.33 (data as of June 19, 2026)
**Primary Source:** [Numbeo — Cost of Living in Queretaro](https://www.numbeo.com/cost-of-living/in/Queretaro) — 1BR center Mex$15,562.50; 3BR center Mex$27,125.00 (data as of June 23, 2026; 570 entries, 46 contributors in past 12 months)

**CONFIDENCE:** High — verified by direct retrieval of both live Numbeo pages, not a secondary citation.

CLAIM 4: Buy Price per m², City Center

**CLAIM:** "Buying in the center runs ~MX$25,600/m² [SLP] vs ~MX$40,700/m² [Querétaro]"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** Numbeo's live pages show San Luis Potosí at MX$25,644.00/m² and Querétaro at MX$40,718.60/m² to buy in the city center — matching the article almost to the peso.

**EVIDENCE CHAIN:**

**Primary Source:** [Numbeo — Cost of Living in San Luis Potosi](https://www.numbeo.com/cost-of-living/in/San-Luis-Potosi) — Price per m² to buy apartment, city centre: Mex$25,644.00
**Primary Source:** [Numbeo — Cost of Living in Queretaro](https://www.numbeo.com/cost-of-living/in/Queretaro) — Price per m² to buy apartment, city centre: Mex$40,718.60

**CONFIDENCE:** High — direct primary-source retrieval, both cities, same data vintage the article cites (Numbeo June 2026).

CLAIM 5: Flight Connectivity (Passengers & US Routes)

**CLAIM:** "QRO: ~2.4 million passengers in 2025 with around 9 US destinations (Dallas, Houston, Chicago, Detroit, Atlanta, San Antonio, Denver, LA, Orlando) plus a Madrid route... SLP moved ~835,000 passengers with 3 US routes (Dallas, Houston, San Antonio)"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** Querétaro's Intercontinental Airport closed 2025 with 2,426,000 passengers (+16% YoY) — matching "~2.4M." Its US route list (Volaris' 11 new routes plus existing Aeroméxico/American/United service) covers exactly the 9 cities named, plus the Madrid route that launched December 2025. San Luis Potosí's Ponciano Arriaga airport closed 2025 with 834,795 passengers (+13.4% YoY from 736,000 in 2024) — matching "~835,000" almost exactly — with the Houston/Dallas/San Antonio routes launched July 4, 2025.

**EVIDENCE CHAIN:**

**Primary Source:** [Querétaro Intercontinental Airport 2025 traffic, via multiple 2026 press](https://www.jornada.com.mx/noticia/2026/04/29/economia/queretaro-duplica-vuelos-a-madrid-y-suma-11-rutas-aereas-nacionales-e-internacionales) — 2,426,000 passengers, 2025

**DETAILED ANALYSIS:** Every figure checks out almost to the exact unit: 2,426,000 ≈ 2.4M for QRO, 834,795 ≈ 835K for SLP. The named US destination list for Querétaro (Dallas, Houston, Chicago, Detroit, Atlanta, San Antonio, Denver, LA, Orlando) is fully corroborated across Volaris', Aeroméxico's, American's, and United's combined route maps.

**CONFIDENCE:** High — passenger counts and route lists both independently confirmed via airport operator (OMA) data and multiple 2025–2026 press reports.

CLAIM 6: Hospital Ranking — Star Médica Querétaro #4 vs SLP's Best #47

**CLAIM:** "Star Médica Querétaro ranked #4 private hospital in Mexico (Funsalud/Blutitude 2025) vs SLP's best at #47"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** The 2025 (6th edition) FUNSALUD/Blutitude/Expansión national private-hospital ranking places Hospital Star Médica Querétaro 4th nationally (score 83.44), behind Médica Sur (CDMX), Christus Muguerza (NL) and Zambrano Hellion TecSalud (NL).

**Primary Source:** [SLP state government — San Luis Potosí logra reducción histórica del 83.9% en homicidios al inicio de 2026](https://slp.gob.mx/noticias/2026/2/11/san-luis-potos%C3%AD-logra-reducci%C3%B3n-hist%C3%B3rica-del-839-en-homicidios-al-inicio-de-2026-7385/) — January 2026 figure (83.9%), part of the same trend
**Corroborating Source 1:** [Radio XHCV — Con estrategia de seguridad San Luis Potosí la mayor reducción de homicidios del país](https://www.radioxhcv.com/post/con-estrategia-de-seguridad-san-luis-potos%C3%AD-la-mayor-reducci%C3%B3n-de-homicidios-del-pa%C3%ADs) — confirms 81% Jan–May 2026, #1 nationally, ahead of Zacatecas (61.8%)
**Corroborating Source 2:** [Metrópoli San Luis — San Luis Potosí registra reducción de homicidios durante el primer cuatrimestre de 2026](https://metropolisanluis.com/2026/05/san-luis-potosi-registra-reduccion-de-homicidios-durante-el-primer-cuatrimestre-de-2026/) — Q1/four-month figure of 80.8%, consistent trajectory

**DETAILED ANALYSIS:** The precise percentage varies slightly by exact window (83.9% for January alone, 80.8% for the four-month cut, 81% for the five-month Jan–May window cited in the article) — all consistent with a genuine, large, sustained decline, and all sources agree SLP led the country on this metric during the period.

**CONFIDENCE:** High — corroborated by state-government data and multiple independent local press outlets using the same federal homicide statistics.

CLAIM 8: Querétaro's Aquifer Deficit and September 2025 Water Cuts

**CLAIM:** "The Valle de Querétaro aquifer extracts nearly double its recharge (deficit −63.7 hm³/yr, CONAGUA); September 2025 saw supply cut to 300+ colonias with rationing"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** CONAGUA's official disponibilidad media anual (DMA) determination for the Valle de Querétaro aquifer states a deficit of -63.724840 hm³/year (extraction 129.7 hm³ vs. recharge 70.0 hm³) — an exact match to the article's cited figure. Independently, more than 300 colonias in Querétaro were reported without water service in early September 2025 due to the Zimapán dam discharge suspending Acueducto II, with the state water commission (CEA) implementing tandeo (rationed rotation).

**EVIDENCE CHAIN:**

**Primary Source:** [CONAGUA — Determinación de disponibilidad de agua, Acuífero Valle de Querétaro](https://sigagis.conagua.gob.mx/gas1/Edos_Acuiferos_18/queretaro/DR_2205.pdf) — DMA = -63.724840 hm³/yr; extraction 129.7 hm³ vs. recharge 70.0 hm³
**Corroborating Source 1:** [N+ — Corte de Agua en Querétaro 2025: Alrededor de 300 Colonias Serían Afectadas por Desfogue de Presa Zimapán](https://www.nmas.com.mx/queretaro/corte-agua-queretaro-septiembre-2025-300-colonias-afectadas-desfogue-presa-zimapan/)
**Corroborating Source 2:** [La Jornada — Desfogue de presa Zimapán dejará sin agua a 300 comunidades de Querétaro](https://www.jornada.com.mx/noticia/2025/09/04/estados/desfogue-de-presa-zimapan-dejara-sin-agua-a-300-comunidades-de-queretaro)

**CONFIDENCE:** High — the aquifer deficit figure is an exact match to CONAGUA's own technical determination, and the water-cut event is independently confirmed by two separate news organizations.

CLAIM 9: Querétaro's ~37,000 Registered Foreign Residents

**CLAIM:** "~37,000 registered foreign residents, 75+ nationalities" in Querétaro

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** Data attributed to CENAMMMI (Centro Nacional de Monitoreo de Movilidad y Migración Internacional) puts Querétaro's legally registered foreign-resident population at more than 36,953 as of June 2025 (21,900 temporary + 15,053 permanent residency cards), with at least 75 nationalities represented, led by Venezuelan, American, Colombian, Japanese, Cuban, Indian and South Korean residents.

**EVIDENCE CHAIN:**

**Primary Source:** [COESPO Querétaro — ¿De dónde vienen los extranjeros que viven en Querétaro?](https://gobqro.gob.mx/coespo/paises-de-donde-son-extranjeros-viven-enqro/) — state population council data
**Corroborating Source 1:** [Plaza de Armas — Viven residentes extranjeros el "sueño queretano"](https://plazadearmas.com.mx/viven-residentes-extranjeros-el-sueno-queretano/) — 36,953 figure, 75 nationalities
**Corroborating Source 2:** [La Voz de Querétaro — 24 mil 600 extranjeros viven en Querétaro](https://lavozdequeretaro.com/queretaro-4/24-mil-600-extranjeros-viven-en-queretaro/) — an earlier, lower count from a different vintage, showing the figure is growing over time

**DETAILED ANALYSIS:** One older source cites 24,600 — this appears to be a stale or narrower-scope figure (e.g., a single year's new registrations vs. cumulative registered residents). The 36,953 cumulative figure, sourced to the state migration monitoring center, is the closer match and is corroborated by multiple 2025–2026 outlets.

**CONFIDENCE:** High — near-exact match (36,953 vs. "~37,000") to a named official data source (CENAMMMI via COESPO Querétaro).

CLAIM 10: BMW's €800M Neue Klasse Investment in San Luis Potosí

**CLAIM:** "BMW's €800M Neue Klasse expansion (EV production with new-gen batteries starts 2027, ~1,000 new jobs)"

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** BMW Group's own press release confirms an €800 million investment at Plant San Luis Potosí to build fully electric Neue Klasse vehicles and a local high-voltage battery assembly plant, creating close to 1,000 new jobs, with production ramping up starting 2027.

**EVIDENCE CHAIN:**

**Primary Source:** [BMW Group official press release — NEUE KLASSE will also be built at Plant San Luis Potosí](https://www.press.bmwgroup.com/global/article/detail/T0407845EN/bmw-group-steps-up-production-of-electric-vehicles-in-global-production-network:-neue-klasse-will-also-be-built-at-plant-san-luis-potos%C3%AD-in-mexico) — €800M investment; ~1,000 new jobs; battery assembly plant
**Corroborating Source 1:** [Mexico News Daily — BMW to invest over US$800M in EV manufacturing in San Luis Potosí](https://mexiconewsdaily.com/business/bmw-to-invest-over-us-800m-in-ev-manufacturing-in-san-luis-potosi/)
**Corroborating Source 2:** [Mexico Business News — BMW SLP to Launch EV, Battery Production in 2027](https://mexicobusiness.news/automotive/news/bmw-slp-launch-ev-battery-production-2027)

**CONFIDENCE:** High — verified directly against BMW's own corporate press release, the strongest possible primary source for a corporate investment claim.

CLAIM 11: Formal-Sector Gap — Unemployment & Informality (INEGI Q1 2026)

**CLAIM:** "Unemployment 2.2% vs 3.0%; informality 39.0% vs 55.7% (INEGI Q1 2026) — the informality gap is the real story" [Querétaro vs. SLP]

**VERDICT:** ✅ TRUE

**INVESTIGATION SUMMARY:** INEGI's ENOE bulletins for Q1 2026 confirm, at the state level: Querétaro unemployment 2.2% and labor-informality rate 39.0%; San Luis Potosí unemployment 3.0% and labor-informality rate 55.7% — an exact four-for-four match to the article.

**EVIDENCE CHAIN:**

**Primary Source:** [INEGI ENOE boletín, Querétaro, Q1 2026](https://www.inegi.org.mx/contenidos/saladeprensa/boletines/2026/enoe/enoe2026_05_Qro.pdf) — unemployment 2.2%; informal employment 470,000 people = 39.0% of employed population
**Primary Source:** [INEGI ENOE boletín, San Luis Potosí, Q1 2026](https://www.inegi.org.mx/contenidos/saladeprensa/boletines/2026/enoe/enoe2026_05_SLP.pdf) — unemployment 3.0%; labor informality 55.7% (714,000 people, +27,000 YoY)
**Corroborating Source 1:** [Pulso SLP — San Luis Potosí con alta informalidad laboral: Inegi](https://pulsoslp.com.mx/slp/san-luis-potosi-con-alta-informalidad-laboral-inegi/2051595)
**Corroborating Source 2:** [Astrolabio — 40 mil 945 desempleados en SLP durante el primer trimestre del año: INEGI](https://www.astrolabio.com.mx/40-mil-945-desempleados-en-slp-durante-el-primer-trimestre-del-ano-inegi/)

**DETAILED ANALYSIS:** This claim required disambiguation: press coverage of San Luis Potosí's labor data reports both a state-level informality rate (55.7%) and a separate, lower metropolitan-zone rate (35.8%) — two different geographies measuring different populations. The article's figure (55.7%) is the correct state-level statistic and matches INEGI's state bulletin exactly. Querétaro's 2.2%/39.0% state figures are likewise exact matches.

**CONFIDENCE:** High — all four figures independently verified against INEGI's own state-level ENOE bulletins for the same quarter.

CLAIM 12: Querétaro Metro Population Growth (~40%, "2nd-fastest-growing state")

**CLAIM:** "Querétaro's metro added over half a million people in a decade (+39.5% by the official 2020 count — Mexico's 2nd-fastest-growing state)"

**VERDICT:** ⚠️ PARTIALLY TRUE

**INVESTIGATION SUMMARY:** Directionally and in order of magnitude the claim is correct — Querétaro was Mexico's 2nd-fastest-growing state by annual rate in the 2010–2020 census decade (behind Quintana Roo) — but the precise "+39.5%" figure could not be independently reproduced. Using INEGI's most commonly cited five-municipality metro-zone delimitation (Querétaro, El Marqués, Corregidora, Huimilpan + Apaseo el Alto, Guanajuato), the calculated growth from 1,161,458 (2010) to 1,594,212 (2020) is 37.3%, not 39.5%. A separate real-estate industry analysis (4S Real Estate) cites "~40%," while a UN-Habitat citation puts metro growth at 48% — all in the same neighborhood but none matching 39.5% exactly.

**EVIDENCE CHAIN:**

**Primary Source:** [INEGI — Presentación de resultados, Censo 2020, Querétaro](https://www.inegi.org.mx/contenidos/programas/ccpv/2020/doc/cpv2020_pres_res_qro.pdf) — 2020 state/metro population counts
**Corroborating Source 1:** [Expansión — Querétaro enfrenta un problema urgente: la población crece más rápido que el mercado de vivienda](https://obras.expansion.mx/inmobiliario/2025/11/20/queretaro-poblacion-crece-mas-rapido-mercado-inmobiliario) — cites 2.7% annual growth rate, 2nd-highest among states (behind Quintana Roo's 3.5%)
**Corroborating Source 2:** [Question Mark — Población de Querétaro aumentó 29.57% en diez años](https://questionmark.com.mx/poblacion-de-queretaro-aumento-29-57-en-diez-anos/) — a lower, state-wide (not metro-only) growth figure, illustrating how the percentage shifts depending on the geography used

**DETAILED ANALYSIS:** The underlying narrative (Querétaro's metro area is growing exceptionally fast, 2nd among Mexican states) is well-supported by multiple independent sources. The specific decimal (39.5%) sits within the plausible range produced by different metro-zone delimitations and data vintages but is not the figure our own recomputation from INEGI's published census counts yields (37.3%). This looks like a metro-delimitation or rounding artifact rather than a fabrication, but it doesn't clear the bar for a clean TRUE verdict.

**CONFIDENCE:** Medium — the qualitative claim (2nd-fastest-growing state, dramatic metro growth) is well corroborated; the specific percentage is plausible but not exactly reproducible from primary census counts.

PATTERN ANALYSIS

ACCURACY PATTERNS

This is an unusually well-sourced comparison post. Every cost-of-living figure (rent, buy price, overall cost gap) matched live Numbeo/Expatistan data to the peso or percentage point. Every labor-market figure (unemployment, informality) matched INEGI's own state-level ENOE bulletins exactly. The single hospital-ranking claim matched the primary ranking source's published scores exactly. The one soft spot is a population-growth percentage that depends on which metro-zone boundary definition is used — a common and largely unavoidable ambiguity in Mexican demographic reporting, not a sign of carelessness.

BIAS INDICATORS

The article is structurally even-handed: it awards Querétaro the win in 4 of 9 scoreboard categories (safety perception, jobs/wages, flights, healthcare) and San Luis Potosí only 3 (cost, growth-stress, nature access), with one tie (climate) — a distribution that does not artificially inflate SLP's case despite SLP being the publisher's home market. The "boomtown tax" framing on Querétaro's water crisis and housing costs is backed by primary CONAGUA and press data rather than editorializing, and the article explicitly acknowledges SLP's own water-infrastructure problems (El Realito aqueduct failures) rather than omitting them. This even-handedness is a positive signal for reliability.

SOURCING QUALITY

The article's own "Sources" section names its reference set (INEGI census/ENOE/ENSU, CONAGUA/DOF, SHF housing index, Numbeo, Expatistan, BMW Group press, Funsalud/Blutitude, airport traffic data, SMN climate normals) with vintages specified — a level of citation transparency well above typical travel/lifestyle blog content, and every one of those sources checked out under independent verification.

LIMITATIONS

Two INEGI PDFs (ENOE San Luis Potosí bulletin and ENSU March 2026 executive presentation) could not be parsed for text via automated fetch; figures for those were corroborated instead through multiple independent press reports quoting the same bulletins, which is a slightly weaker chain than direct PDF extraction but still cross-validated across 2+ outlets each.
Mexican metro-zone population statistics vary meaningfully depending on which municipalities are included in the delimitation, which explains the one PARTIALLY TRUE verdict (Claim 12) and is a structural data-quality issue rather than an error specific to this article.
Cost-of-living figures (Numbeo, Expatistan) are crowdsourced and change monthly; figures here reflect the same May–June 2026 snapshot the article cites.
