Business Analyst Desktop may be used to obtain the population density of an area. Population density data are required to determine the growth of a population, for example.
However, the population density calculated manually using the Field Calculator returns a different value compared to the population density data recorded in Business Analyst Desktop.
The discrepancy in the values is due to the different coordinate system used to calculate the data. The Business Analyst Desktop population density data is recorded using the State Plane Coordinate System. In the manual calculation, the area populated in the attribute table is calculated using the Calculate Geometry tool. The tool's data frame setting uses the WGS 1984 Web Mercator coordinate system by default.
To obtain identical population density values, follow the instructions described below:
