37M מקסיקני-אמריקאי הגדול ביותר-יחיד-מסדרון מסגרת תפוצות (עוגן בעיטה §13)

This route documents the overarching framework of Mexican diaspora identity, rights, and legal status — the largest single bilateral diaspora corridor in the world by absolute numbers. It is not a discrete nationality acquisition pathway but an analytical framework that contextualizes and connects the other routes in the XCT bucket and the post-2021 DSC routes.

Population figures:

• ~37.2 million Mexican-Americans (US Census 2020 / Pew Research 2021 ACS) — persons of Mexican origin or descent in the United States
• ~12 million Mexicans currently residing abroad (IME 2017 baseline: 11.85M; estimated ~12M by 2024) — of whom 97.23% reside in the United States
• ~49 million persons total in the MX-US diaspora corridor (37.2M Mexican-American + 12M Mexico-origin in US = ~49M in US alone)

The Treaty of Guadalupe Hidalgo (MX-BIL-GUADALUPE-1848) is the foundational legal event establishing the Mexican-American identity: the approximately 75,000-100,000 Mexican citizens in the ceded territories who became US citizens by default in 1848-1849. From that 19th-century origin, subsequent waves of economic migration — particularly in the 20th century (Bracero Program 1942-1964, post-NAFTA economic restructuring 1994+, 21st-century migration) — expanded the population to its current scale.

The 2021 jus sanguinis reform (CPEUM Art 30 A II — MX-DSC-03) is the most significant legal event for this population since 1848: by eliminating the requirement that a transmitting Mexican parent be born in Mexico, the reform opened unlimited generational jus sanguinis for Mexican-Americans beyond the first generation. An estimated 37+ million persons potentially qualify for Mexican nationality certification who did not previously qualify, subject to documentary chain requirements.

The apostilla elimination (DOF junio 2024 — CNDOC Arts 314 + 1144) removed a major bureaucratic barrier: US-issued birth certificates and civil documents no longer require apostilles when presented for Mexican nationality proceedings, dramatically reducing the cost and complexity of documentation chains.

• CPEUM Art 30 A II (post-2021): Unlimited generational jus sanguinis — core legal enabler for diaspora nationality recovery
• CPEUM Art 35: Political rights for Mexican citizens — basis for VMRE extraterritorial voting
• CPEUM Art 36: Civic obligations of Mexican citizens
• LGIPE Libro VI Título II: VMRE extraterritorial voting system (MX-XCT-VMRE-01)
• IME/IMME framework (Decreto DOF 2003-04-16): Institutional coordination authority
• SRE 53-consulate network: Operational service delivery (MX-XCT-CONSULAR-01)
• DOF junio 2024 CNDOC Arts 314 + 1144: Apostilla elimination for nationality-acreditando documents
• Treaty of Guadalupe Hidalgo 1848: Historical origin anchor (MX-BIL-GUADALUPE-1848)
