While you might have listed yourself as “Puerto Rican,” or “Mexican,” or “Hispanic,” in the 2010 census, this is not how you are going to find your bisabuela or your abuela if she was in the U.S. and counted in the newly released records of the 1940 census.
“The terms “Hispanic” or “Latino” were not used then,” says Mark Hugo López, of the Pew Hispanic Center. It was not until the 1970 census that Hispanics could identify themselves as such.
