Population data from the 2010 Census is now available for use in MARPLOT

On April 5, 2011 the 2010 Census Block level population files were made available for download in MARPLOT.  As other levels (Block Groups, Counties, and Tracts) are released, we will make them available as well.  Note that if you download the new population files at this time, MARPLOT will only use the 2010 data for "get population" functions where the radius is less than 25 miles (otherwise it uses different population levels, such as Tracts, which still have 2000 data).

Updating Your Existing Population Data

• After the data file download is complete, exit MARPLOT.
• Browse to the location of your MARPLOT program folder (e.g., C:\Program Files\MARPLOT).
  
• Double-click on the "reindex.bat" file, which will allow MARPLOT to recognize the newly-downloaded population files.
• You can then restart MARPLOT, and the new population data should be available.      

Getting New Population Data

When you download census block population files (either with a Get Population feature or using the Download Manager), they will automatically be the 2010 Census files. However, if you download other Census levels (e.g., Block Groups, Counties, and Tracts) be aware that those files will still be 2000 data, and you may need to update those to 2010 data at a later date, when they become available
