  WORLD GRIDS (30 arc-second cells):

  Population -	A subdirectory containing the ArcGIS grid (lspop2012) of the 
		population.  There is also a "Layer" file (lspop2012.lyr) for ArcGIS.

                Each cell value represents the number of people in that 30 arc-second
                cell.

  Admin1 -	A subdirectory containing the ArcGIS grid (world_admin1) of the 
  with		countries/sub-countries.  These are the standard Level 1 Administrative
  Demographic	Boundaries.
  Factors
		The attribute table for this grid contains the age-sex factors for the 
		"admin1" units.  The factors can be used to create various demographic 
		grids for your own needs.
		
		For example, to produce a population grid for females, ages 5-9:

			1. Set the Analysis window to your needs. Make sure the 
			   cellsize is 30 arc-seconds, i.e., 0.0083333333333 degrees.
			2. Use the Map Calculator in the Analysis Menu with the 
			   command:

				( [lspop2012] * [world_admin1 . Pf5_9])

		Also contains a DBF (demog_admin1.dbf) for the demography factors of
		each admin1 area. 

  
  Country -	A subdirectory containing the ArcGIS grid (countries) of the 
		countries.  These are the standard Country Boundaries.

		Also contains a DBF (countries.dbf) giving the country name for each
		country "number" in the grid and has demographic factors similar to the
		Admin1 table.


  AreaGrid -    A subdirectory containing a grid of areas of 30 arc-second cells.  The 
                data table (VAT) contains the cell areas in the field: [Area].  The
                units are square kilometers.
