Access is Free to Public for Most Comprehensive Mexican Census Published Online

PROVO, UTAH – (September 16, 2011) –, the world’s largest online family history resource, today announced a significant addition to its growing collection of online Mexican and Hispanic historical records. With nearly 13 million records, the newly available 1930 Mexico National Census (El Quinto Censo General de Población y Vivienda 1930, México) is the most comprehensive historical Mexican census available online[1]. It is estimated that this census counted approximately 90 percent of the population, therefore for nearly 30 million Americans who can trace their families to Mexico, it provides a valuable gateway to begin researching Mexican family history, especially if family, vital or religious records are lost.

Mexico’s first formally recognized federal or national census was taken in 1895. Starting in 1900, censuses were taken every 10 years, making the 1930 Mexico Census the fifth official government census, or formally the Fifth General Census of Housing and Population. This particular census is significant in Mexican history as federal officials sought to make it a vehicle for national unity. A successful campaign urging citizens to take part as a civic duty resulted in an extremely high participation rate – the primary reason why the 1930 Mexican Census is considered the best Mexican census conducted in the 20th century.

Edward James Olmos, Academy Award nominated actor and noted philanthropist, is working with to trace his family’s Mexican history using information found in the 1930 Mexico National Census.

“Like so many Latinos, I’m proud of my heritage and want to preserve that legacy for future generations,” said Olmos. “With resources like the 1930 Mexico National Census, families can now trace their ancestors to Mexico and gain a greater understanding of where they came from.”

The 1930 Mexico National Census provides a wide spectrum of details about individuals and families and can offer valuable insight into their lives. In addition to demographic data such as name, age, gender, birthplace, address and marital status, the census form also recorded nationality, religion, occupation, real estate holdings, literacy and any physical or mental defects. The millions of records in the collection reveal some interesting statistics about life in Mexico in 1930:

  • The most common given female name was Maria and the most common given male name Juan.
  • The three most common surnames were Hernandez, Garcia and Martinez.
  • Nearly 18% of the population were recorded as Soltero [single], 11% were Casado por lo Civil y la Iglesia [civil and church marriage], 10% were Casado por la Iglesia [church marriage] and 8% were Union Libre [free union—living together without marriage].
  • The four most populous Mexican states were Puebla, Veracruz, Jalisco and Oaxaca.
  • Famous Mexicans found in the collection include Maria Félix (1914–2002), who was among the best-known Mexican actresses and Carmello Torres Fregoso (Bernardo del Carmen Fregoso Cázares; 1927-2003), a renowned bullfighter who later became a successful businessman.

“As the United States is home to the second largest Mexican community in the world, Mexican-Americans comprise 10 percent of the total U.S. population therefore it is fitting that the world’s largest online family history resource now has an expansive collection to serve this important demographic,” said Josh Hanna, Executive Vice President.

While the 1930 Mexico Census is the newest and largest collection of Mexican records on, there are a number of other collections that may be helpful when conducting Mexican family history research, including Border Crossings: From Mexico to U.S., 1895-1957; Nuevo Leon and Tamaulipas, Mexico, Selected Parish Records, 1751-1880; and the Spanish-American Family History Guide.
