aSource for counties: 2000 Census Gazetteer File (extract of Summary File 1) (http://www.census.gov/geo/www/gazetteer/); total 2000 population of 281.4 million.

bPlaces include all incorporated places plus census-designated places in Hawaii; census-designated places in the other states will have estimates published for them (see Table 2-5) but are not recognized for purposes of oversampling; see note a above for source of estimates.

cMinor civil divisions (not coterminous with places) are recognized in 12 states for purposes of oversampling (Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin); they are recognized in additional states for publication but do not benefit from oversampling in these states; see note a above for source of estimates.

dPopulation size for school districts is as of 2003; some school districts (for example, elementary and secondary districts) overlap in population, so the population base for percentages is 314.6 million and not the 2003 population of 290.8 million. Source for school districts: 2003 population estimates (http://www.census.gov/hhes/www/saipe/school/sd03layout.html).

eSee Table 2-3a for oversampling rates for blocks in small jurisdictions of fewer than 500 people, 500-2,000 people, and 2,000-3,000 people.
