I am using ArcMap
Out of a raster, I reclassified it into only having the urban areas.
- I ran this through zonal statistics and got the area of the urban area (in meters, which I presume are in square meters because it is area, correct?).
- After getting the zonal stats, I joined into a census tract file which has immigrant population data (ex. dominicans, europeans,etc.).
- I want to calculate the population density by square kilometer of these urban areas (1000 person/km2). What I did was taking the area field (results of the zonal stats) and dividing the presumed square meters into 1,000,000 to get the square kilometers.
- After which, I divided the population group by the square km of that tract.
My question is, did I did this correctly, did I missed a step or are the results of the zonal stats not square meters?
