The Uniform Crime Reporting program and the National Crime Victimization
Survey together provide a complementary picture of crime in the U.S.
NCVS estimates are based on interviews with a
nationally representative sample of persons in
U.S. households. UCR estimates are based on counts of
crimes reported by law enforcement agencies and are
weighted to compensate for incomplete reporting.
The NCVS does not measure crimes against children
age 11 or younger. Also, it does not measure crimes
against persons who are homeless or live in institutions
(e.g., nursing homes and correctional institutions) or on
Typically, NCVS and UCR property crime rates are
calculated differently. UCR property crime rates are
per capita (number of crimes per 100,000 persons),

whereas the NCVS rates for these crimes are per
household (number of crimes per 1,000 households), so
the NCVS rates are higher. There were 2.2 NCVS persons
age 12 or older for each NCVS household in 2018.
Moreover, because the number of households may not
grow at the same rate each year as the total population,
trend data for rates of property crimes measured by the
two programs may not be entirely comparable.
Taken together, these two measures of crime provide
a more comprehensive picture of crime in the U.S. For
additional information about the differences between
the NCVS and UCR, see The Nation’s Two Crime Measures
(NCJ 246832, BJS web, September 2014).
