For instance,

statistics were used to construct the following

graphs, which show the fastest growing U.S. cities

(population over 100,000) in 2008 by percent

increase in population, U.S. cities with the largest

numerical increases in population, and the

regions where the cities are located.

For the 2010 Census, the Census Bureau sent

short forms to every household. Short forms ask

all members of every household such things as

their gender, age, race, and ethnicity. Previously,

a long form, which covered additional topics, was

sent to about 17% of the population. But for the

first time since 1940, the long form is being

replaced by the American Community Survey,

which will survey about 3 million households a

year throughout the decade. These 3 million

households will form a sample. In this course,

you will learn how the data collected from a

sample are used to infer characteristics about the

entire population.
