Long form resources provide detailed information such as income, education and poverty down to the block group (the block group is the smallest geography at which detailed variables are available).
The long form is the long questionnaire given out to 1 in 6 households. Summary File 3 (SF3) and Summary File 4 (SF4) come from the long form. Topics include "income, education, occupation, ancestry, disability, foreign birth, commuting, household financial arrangements, year housing structure built and many other population and housing subjects."

Short form resources provide basic demographics down to the census block level.
The short form is the short questionnaire given out to all households. Summary File 1 (SF1) and Summary File 2 (SF2) come from the short form. Only basic demographics are available, but they are available down to the smallest geographic unit (the census block). Data available include "age, sex, race, Hispanic/Latino origin, households, families, housing units, and owner/renter status."
