US Census Bureau - Quite possibly the best site for human statistical information. Inundated with links relating to the numeration questions answered by the general population on the Census Bureau questionnaires. Pertinent information is drawn from these forms such as the total population count for the country, race information, age data, and educational attainment of the population. This information is then disseminated down to the state level. This information is what is used in formulas to find out how much federal money is given yearly to each state. It is then broken down to the county level. After this it is taken down to the city, town, or municipality level. Finally it is broken down to the block and tract level. At every level the information is useful for finding out how many people are in a given area so that it can be used in formulas for funding special projects such as schools being built. Even stop lights being built for neighborhood safety.
