national
The Population Estimates Program produces monthly national population
estimates by age, sex, race, and Hispanic origin for the United States.
These estimates cover four different populations: resident population,
resident population plus Armed Forces overseas, civilian population, and
civilian noninstitutional population. All reference dates in the monthly
national estimates refer to the first of the month.
NOTE: All population figures for the year 2000 shown here (including
April 1, 2000) are based on the 1990 Census; they do not reflect
Census 2000 counts.

state
The Population Estimates Program produces for states each year: total
population estimates, estimates by age and sex, and estimates by race
and Hispanic origin. The release of total population estimates at the
end of the calendar year also includes demographic components of change.
In the spring, the Program releases population by age and sex, presenting
tables for different age groupings as well as single year of age. A third
release in the summer presents estimates by age, sex, race, and Hispanic
origin. All estimates are for the resident population unless noted
otherwise. The reference date for state estimates is July 1.
NOTE: All population figures are based on the 1990 Census; they do not
reflect Census 2000 counts.

place and county subdivision
The Population Estimates Program (PEP) annually releases total population
estimates for places and, in selected states, county subdivisions (minor
civil divisions). The most recent release was in 2000, covering the years
1991 to 1999. The reference date for place and county subdivision population
estimates is July 1. For the 1999 estimates time series, the 1990 base
populations for all areas were updated for the first time since
the 1990 Census. The new time series reflects boundary and other geographic
changes. See "Geographic changes" below for additional information.
PEP produces estimates for all incorporated places; these places include
cities, as well as towns, boroughs, and villages, depending on the state.
PEP also produces estimates for governmentally functioning minor civil
divisions, which are legally defined county subdivisions (see
Population Estimates: Concepts). The population
estimates shown in these tables do not reflect any subsequent modifications
brought about through the formal challenge process.
NOTE: All population figures are based on the 1990 Census; they do not
reflect Census 2000 counts.

metropolitan areas
The Population Estimates Program releases metropolitan area total
population estimates in odd-numbered years, using current metropolitan
areas as defined by the Office of Management and Budget. The most recent
release was in 2000, covering the years 1991 to 1999. The reference date
for metropolitan area population estimates is July 1.

puerto rico municipios
The Population Estimates Program releases Puerto Rico municipio total
population estimates and demographic components of change each year. The
reference date for these estimates is July 1.
A municipio is the governmental unit that is the primary legal subdivision
of Puerto Rico; the Census Bureau treats the municipio as the statistical
equivalent of a county.
household and housing unit
The Population Estimates Program each year produces estimates of
households, housing units, distribution of households by age of
householder, and persons per household, by state. The reference date for
these estimates is July 1.
terms & definitions
- What is a population estimate?
The Census Bureau’s Population Estimates Program (PEP) produces
July 1 estimates for years after the last published decennial
census (1990), as well as for past decades. Existing data series
such as births, deaths, Federal tax returns, medicare enrollment,
and immigration, are used to update the decennial census base
counts. PEP estimates are used in Federal funding allocations,
in setting the levels of national surveys, and in monitoring
recent demographic changes. A methodology reference accompanies
most of our population estimates offerings.
- How are estimates different from projections?
There is not a distinct dichotomy between population estimates
and population projections, but there are some differences in
time reference and derivation. Estimates usually are for the past,
while projections typically are for future dates. Estimates
generally use existing symptomatic data, for example, (births,
deaths, migration), collected from various sources. Projections
must assume future trends for fertility, mortality, and other
demographic processes. At the Census Bureau, the population
projections use the latest available estimates as starting points.
In our current product offerings the user may see both an estimate
and a projection available for the same reference date, which
may not agree because they were produced at different times. In
such cases, estimates are the preferred data.
- Revisions to estimates and geographic detail
With each new issue of July 1 estimates, PEP revises estimates
for years back to the last census. Previously released estimates
become superseded. Revisions to estimates are usually due to
input data updates, changes in methodology, or legal boundary
changes. The frequency of estimates and availability of demographic
detail vary by geographic level.
- Why does the Census Bureau produce estimates?
The legal requirement for the Census Bureau to produce subnational
population estimates is given in Title 13 of the U.S. Code. Title
13 states that: "During the intervals between each census
of population required under section 141 of this title, the
Secretary, to the extent feasible, shall annually produce and
publish for each State, county, and local unit of general purpose
government of fifty thousand or more, current data on total population
and population characteristics and, to the extent feasible, shall
biennially produce and publish for units of general purpose
government current data on total population." The reason for
producing estimates is given in Section 183 of Title 13:
"Except as provided in subsection (b), for the purpose of
administering any law of the United States in which population
or other population characteristics are used to determine the
amount of benefit received by State, county, or local units of
general purpose government, the Secretary shall transmit to the
President for use by the appropriate departments and agencies of
the executive branch the data most recently produced and published
under this title."
In other words, the Census Bureau produces subnational estimates
for use in the allocation of funds to state, county and local
governments. For this reason, the Census Bureau produces population
estimates for general-purpose functioning governments. These
governments have elected officials who can provide services and
raise revenue. In addition to states and counties, incorporated
places and minor civil divisions also serve as general-purpose
functioning governmental units.
