Beginning in 1790, the United States has conducted one national census every ten years. In an effort to provide detailed information more frequently, beginning in 2005, the Census Bureau also began conducting the nationwide American Community Survey (ACS) to collect data on a broad range of subjects on a regular basis. This survey was designed to supplement the brief “short form” decennial census which is still administered. The ACS has an annual sample size of about 3.5 million addresses, with survey information collected nearly every day of the year. Data are pooled across a calendar year to produce estimates for that year. As a result, ACS estimates reflect data that have been collected over a period of time rather than for a single point in time as in the decennial census.

Just who is a Hispanic? One approach defines a Hispanic or Latino as a member of an ethnic group that traces its roots to 20 Spanish-speaking nations from Latin America and Spain itself (but not Portugal or Portuguese-speaking Brazil). The other approach is much simpler. Who's Hispanic? Anyone who says they are.
