She was previously the president of the Association of Professional Genealogists. Updated October 03, 2018 Because personal census data less than 72 years old is protected by confidentiality, names are not entered into the databases used by the U.S. Census Bureau to tabulate statistics in various categories. For this reason, a surname study across the entire census population is not possible. Thus, this list of the most common surnames from the 1990 census was created by the U.S. Census Bureau from a sampling of 7.2 million census records gathered as part of an independent post-enumeration study conducted in the summer of 1990. Why is this important? For the most common US surnames, the estimated population percentages from the sampling probably reflect the population at large with a fairly high degree of accuracy. However, the survey intentionally oversampled both blacks and Hispanics, so certain surnames such as Garcia, Rodriguez, Gomez, and Washington may be over-represented. Because the sample involved certain regional areas, it is also possible that some less-common surnames made their way onto the list because a large percentage of family members happened to live within one of the areas studied. Thus, this list is not an entirely accurate representation of the U.S. population in 1990 as a whole, although it is likely to be generally close. Either way, it's fun info.Curious about how times have changed?
