NGS In The News Center Of Population Project NGS homepage NOAA homepage

In a project co-sponsored by NOAA's National Ocean Service (NOS), the Census Bureau, and the American Congress on Surveying and Mapping (ACSM), many states are in the process of officially monumenting their Year 2000 Center of Population by setting commemorative markers. Most recently, Missouri, New Jersey and Washington have set and performed GPS observations of their 2000 Census Center of Population monuments.  A number of states have now set such markers. In a cooperative effort, the Census Bureau provides the location of the state population centers, and NOS provides the guidelines for placement of the marker. ACSM coordinates the monument setting and observation performed by state professional surveyors. This is an excellent example of what collaboration between the private sector and Federal, state and local governement surveying and mapping professionals can achieve. It is expected that all state Center of Population sites will be included in NOAA's National Spatial Reference System, which will allow surveyors and others to utilize the markers. Click on the map below for information about a particular state's Center of Population.

Please contact Dave Doyle for more information .

The National Geodetic Survey (NGS), in cooperation with individual state professional surveying associations and other organizations, would like to encourage the setting of a commemorative geodetic control monument at or near the computed location of each state's population center as determined by the U.S. Census Bureau. Each state's center is shown on the map below, and the contact information for each state may be obtained by clicking on that point.
