Activating any of the 'Prayer Coverage' layers will cause your map to be divided into sections. These sections will change depending on the current scale of your map. The current map scale can be found in the bottom-right corner of the map. At 1 mile/2 kilometers or less, the map will be divided into Census Block Groups. These are geographic divisions used in the census that typically contains between 600 and 3000 residents. At 2 miles/5 kilometers or more, the map will be divided into counties, parishes, and boroughs.
The sections of the map will be shaded a different color depending on the percentage of homes in that section that meet the criteria. View the legend in the control panel to decipher the information.
