The NOEP demographics database contains
population and housing data for the coastal states and counties
from the 1970 to 2010 censuses, with yearly estimates from 2001 to
2019. Population and housing data are also
available for zip codes adjacent to the shoreline for 1990 and 2000.
Population & housing data may be selected for the U.S., all coastal
states, individual coastal states, and coastal counties. Additionally,
data may be selected from the database by
. Optional coastal regions
can also be selected for output of shoreline, coastal zone, watershed, and
other county totals. Population & housing densities and area square miles
options also available for all selections.
Population and housing data are gathered from the
U.S. Census Bureau
online databases for all coastal counties and states.
Coastal counties are those defined by the coastal states in accordance
with the Coastal Zone Management Act of 1972, which includes the Great
Lakes states. U.S. national population and housing data also are
provided for the above years for comparison.
For recent years, the data are extracted from the Census's
data tables using their Application Programming Interface (API)
and are compiled into the NOEP database. Estimates for the Virgin
Islands are compiled from other sources, when available.
Land areas, in square miles, are also available from the Population and
Housing search pages. These areas represent the dry land totals and
exclude lakes, rivers, and other major bodies of water. Land area
values are compiled from the U.S. Census Bureau and ESRI GIS tables.
