Question: When was gay marriage made legal in the place where Universidad Tecnologica is located?

full_context: Document 1: Southern California: The Tech Coast is a moniker that has gained use as a descriptor for the region's diversified technology and industrial base as well as its multitude of prestigious and world-renowned research universities and other public and private institutions. Amongst these include 5 University of California campuses (Irvine, Los Angeles, Riverside, Santa Barbara, and San Diego); 12 California State University campuses (Bakersfield, Channel Islands, Dominguez Hills, Fullerton, Los Angeles, Long Beach, Northridge, Pomona, San Bernardino, San Diego, San Marcos, and San Luis Obispo); and private institutions such as the California Institute of Technology, Chapman University, the Claremont Colleges (Claremont McKenna College, Harvey Mudd College, Pitzer College, Pomona College, and Scripps College), Loma Linda University, Loyola Marymount University, Occidental College, Pepperdine University, University of Redlands, University of San Diego, and the University of Southern California.
Document 2: Mexico City: The second largest higher-education institution is the National Polytechnic Institute (IPN), which includes among many other relevant centers the Centro de Investigación y de Estudios Avanzados (Cinvestav), where varied high-level scientific and technological research is done. Other major higher-education institutions in the city include the Metropolitan Autonomous University (UAM), the National School of Anthropology and History (ENAH), the Instituto Tecnológico Autónomo de México (ITAM), the Monterrey Institute of Technology and Higher Education (3 campuses), the Universidad Panamericana (UP), the Universidad La Salle, the Universidad del Valle de Mexico (UVM), the Universidad Anáhuac, Simon Bolivar University (USB), the Alliant International University, the Universidad Iberoamericana, El Colegio de México (Colmex), Escuela Libre de Derecho and the Centro de Investigación y Docencia Económica, (CIDE). In addition, the prestigious University of California maintains a campus known as "Casa de California" in the city. The Universidad Tecnológica de México is also in Mexico City.
Document 3: Mexico City: The politics pursued by the administrations of heads of government in Mexico City since the second half of the 20th century have usually been more liberal than those of the rest of the country, whether with the support of the federal government—as was the case with the approval of several comprehensive environmental laws in the 1980s—or through laws recently approved by the Legislative Assembly. In April of the same year, the Legislative Assembly expanded provisions on abortions, becoming the first federal entity to expand abortion in Mexico beyond cases of rape and economic reasons, to permit it regardless of the reason should the mother request it before the twelfth week of pregnancy. In December 2009, the Federal District became the first city in Latin America, and one of very few in the world, to legalize same-sex marriage.
Document 4: Mexico City: The economic reforms of President Carlos Salinas de Gortari had a tremendous effect on the city, as a number of businesses, including banks and airlines, were privatized. He also signed the North American Free Trade Agreement (NAFTA). This led to decentralization and a shift in Mexico City's economic base, from manufacturing to services, as most factories moved away to either the State of Mexico, or more commonly to the northern border. By contrast, corporate office buildings set their base in the city.
Document 5: Mexico City: For administrative purposes, the Federal District is divided into 16 "delegaciones" or boroughs. While not fully equivalent to a municipality, the 16 boroughs have gained significant autonomy, and since 2000 their heads of government are elected directly by plurality (they were previously appointed by the head of government of the Federal District). Given that Mexico City is organized entirely as a Federal District, most of the city services are provided or organized by the Government of the Federal District and not by the boroughs themselves, while in the constituent states these services would be provided by the municipalities. The 16 boroughs of the Federal District with their 2010 populations are:
Document 6: Mexico City: In response to the demands, in 1987 the Federal District received a greater degree of autonomy, with the elaboration the first Statute of Government (Estatuto de Gobierno), and the creation of an Assembly of Representatives.[citation needed] In the 1990s, this autonomy was further expanded and, starting from 1997, residents can directly elect the head of government of the Federal District and the representatives of a unicameral Legislative Assembly (which succeeded the previous Assembly) by popular vote.
Document 7: UPIITA: UPIITA is currently one of the most demanded engineering schools in Mexico. Thousands of students apply each year through an admission test, but only a few hundred (around 300) are accepted. It stands as one of the best and most demanding engineering schools in the country, where many teachers work in scientific research.
Document 8: Centro de Investigación y Docencia Económicas: The Centro de Investigación y Docencia Económicas ("Center for Research and Teaching in Economics"; CIDE) is a Mexican center of research and higher education, specialized in the fields of social sciences, with an international-grade level of excellence. It is financed with public resources. It is considered one of Mexico's top think tanks.
Document 9: Mexico City: Mexico City is home to some of the best private hospitals in the country; Hospital Ángeles, Hospital ABC and Médica Sur to name a few. The national public healthcare institution for private-sector employees, IMSS, has its largest facilities in Mexico City—including the National Medical Center and the La Raza Medical Center—and has an annual budget of over 6 billion pesos. The IMSS and other public health institutions, including the ISSSTE (Public Sector Employees' Social Security Institute) and the National Health Ministry (SSA) maintain large specialty facilities in the city. These include the National Institutes of Cardiology, Nutrition, Psychiatry, Oncology, Pediatrics, Rehabilitation, among others.
Document 10: Universidad Interglobal: Universidad Interglobal (The Interglobal University) is a Mexican private institution with six campuses located in Guerrero, Mexico City, Mexico State, Hidalgo, Querétaro, and Yucatán. The university offers study plans for regular students, students that work in the mornings, and for people who are only available on weekends.
Document 11: Mexico City: During Andrés López Obrador's administration a political slogan was introduced: la Ciudad de la Esperanza ("The City of Hope"). This motto was quickly adopted as a city nickname, but has faded since the new motto Capital en Movimiento ("Capital in Movement") was adopted by the administration headed by Marcelo Ebrard, though the latter is not treated as often as a nickname in media. Since 2013, to refer to the City particularly in relation to government campaigns, the abbreviation CDMX has been used (from Ciudad de México).
Document 12: Mexico City: Unlike those of Mexican states' schools, curricula of Mexico City's public schools is managed by the federal Secretary of Public Education. The whole funding is allocated by the government of Mexico City (in some specific cases, such as El Colegio de México, funding comes from both the city's government and other public and private national and international entities).[citation needed] The city's public high school system is the Instituto de Educación Media Superior del Distrito Federal (IEMS-DF).
Document 13: Mexico City: Between 2000 and 2004 an average of 478 crimes were reported each day in Mexico City; however, the actual crime rate is thought to be much higher "since most people are reluctant to report crime". Under policies enacted by Mayor Marcelo Ebrard between 2009 and 2011, Mexico City underwent a major security upgrade with violent and petty crime rates both falling significantly despite the rise in violent crime in other parts of the country. Some of the policies enacted included the installation of 11,000 security cameras around the city and a very large expansion of the police force. Mexico City has one of the world's highest police officer-to-resident ratios, with one uniformed officer per 100 citizens.
Document 14: Mexico City: Up to the 1990s, the Federal District was the most populous federal entity in Mexico, but since then its population has remained stable at around 8.7 million. The growth of the city has extended beyond the limits of the Federal District to 59 municipalities of the state of Mexico and 1 in the state of Hidalgo. With a population of approximately 19.8 million inhabitants (2008), it is one of the most populous conurbations in the world. Nonetheless, the annual rate of growth of the Metropolitan Area of Mexico City is much lower than that of other large urban agglomerations in Mexico, a phenomenon most likely attributable to the environmental policy of decentralization. The net migration rate of the Federal District from 1995 to 2000 was negative.
Document 15: Mexico City: Mexico City, being the seat of the powers of the Union, did not belong to any particular state but to all. Therefore, it was the president, representing the federation, who used to designate the head of government of the Federal District, a position which is sometimes presented outside Mexico as the "Mayor" of Mexico City.[citation needed] In the 1980s, given the dramatic increase in population of the previous decades, the inherent political inconsistencies of the system, as well as the dissatisfaction with the inadequate response of the federal government after the 1985 earthquake, residents began to request political and administrative autonomy to manage their local affairs.[citation needed] Some political groups even proposed that the Federal District be converted into the 32nd state of the federation.
