Mexico National Census, 1930 - FamilySearch Historical Records

 Mexico

What is in This Collection?
Population schedules consist of large sheets with rows and columns. The sheets are arranged in bundles by municipality and then by place, such as city, village, or ranch. The original schedules are at the National Archives (Archivo General de la Nación) in Mexico City. The records have been preserved on microfilm by the Genealogical Society of Utah

While earlier attempts were made to enumerate the Mexican population, the 1895 census was considered the first federal or national census. Beginning in 1900, censuses were conducted every 10 years. The 1930 census was conducted on May 15 and was the first census in which returns were processed centrally. Because of this, most of the sheets still exist. This census is widely recognized as one of Mexico’s best planned and executed censuses, and it is also the only one accessible to the public. Due to under counting and some record loss, primarily for the Federal District, the 1930 census covers about 78 percent of the population, not 90% as previously reported. (This figure is based on 12.8 million persons in the Ancestry.com database extracted from this census compared with a total population in 1930 for all of Mexico in 1930 of 16,552,722 (see Mexico Population 1930). Since the population of Mexico City was 1,029,000 in 1930, there were record losses in areas beyond the Federal District as well, accounting for another 2 million plus persons not covered in the database placed online by Ancestry.com in September 2011.

The Mexico 1930 Census is usually reliable, depending on the knowledge of the informant and the care taken by the census enumerator. Realize that information may have been given to a census taker by any member of the family or even by a neighbor.

I Found the Person I Was Looking For, What Now?

 * Add any new information to your records
 * The Mexico 1930 Census is the best source to quickly identify a family group and residence. With the information found, take your ancestor’s age, place of residence, and birth state (if available) to search for him/her in other records. The census identifies other people living in the household and may identify people for whom other records simply do not exist. You need to know the name of your ancestor for those places that are indexed. If the ancestor has a common name, you must know the place of residence to determine which index entry is the correct one. If you do not find your ancestor in the index, use the place of residence and search that place page by page. An important clue found in the Mexico 1930 Census is found in the answer to the question of whether the person was married civilly or by the church. The answer to this question will lead either to find a marriage record in the Civil Registration or the Marriage records of the Catholic Church
 * Use the marriage information to help you find your ancestor in the Catholic Church and Civil Records for the state they reside in
 * Accept the ages with caution
 * Given names may not always be the same as the names recorded in vital records
 * Names of people as well as places may be spelled as they sound
 * Compile information for every person who has the same surname as your ancestor; this is especially helpful in rural areas or if the surname is unusual

I Can’t Find The Person I’m Looking For, What Now?

 * If the family is not at the suspected address, search the surrounding area
 * Check for variants of given names, surnames, and place names. Transcription errors could occur in any handwritten record; also, it was not uncommon for an individual be listed under a nickname or an abbreviation of their name. Click here for a list of Spanish name abbreviations
