Mexico, Baja California and Baja California Sur, Civil Registration - FamilySearch Historical Records

What is in This Collection?
This collection includes civil records for Baja California and Baja California Sur and covers from 1860 to 2004.

Records, such as birth, marriages, and deaths, are organized by state and then by municipality/city. Early records were handwritten in narrative style; later records were handwritten in formatted registers. These records are written in Spanish; also see the section For Help Reading These Records for translation helps.

Civil records in Mexico cover about 90 to 95% of the population. Beginning in 1859, the Mexican government began requiring births, marriages, and deaths to be recorded by civil authorities on a municipality/district level. Although these records are a great source of genealogical information, they are not complete as civil registration wasn't strictly enforced in Mexico until 1867 and people did not always comply. For this reason, church registers should be used alongside the civil records. The civil records of Mexico have been preserved relatively well. Only some of the older registers may have some physical damage. However, in general they are in good condition to extract genealogical information.
