Approximately 16 percent of households received a "long form" of the 2000 census, which contained over 100 questions. Full documentation on the 2000 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.
This was the first census in which a state—California—recorded a population of over 30 million, as well as the first in which two states—California and Texas—recorded populations of more than 20 million.
