In this research population data of 2011 andGeoEye imagery of 2010 with 0.6 m resolution were used to get the final Population Density Map based on build up area/square km of Saltlake City. GeoEye image for Saltlake city is suitable for accusation of builtup area because of 0.6m resolutionand secondary population data were designed with Personal Geodatabase(PGDB). The high population densities were found in 4, 19 and 20 sector that is 103.58, 103.34, and 119.77Sq.Km/Person,where the area were measured 187.81, 288.49, 161.89 sq. km respectively. The sector no.9, 15 and 21 were found as medium density. Rests of sector were found as low density. It was highly appreciate that sector no. 19 is a slum and having highly dense built up area with 9336 population. But for sector 4 and 20 builtup areas are highly dense with arranged multistory building but having 8161 and 7927 population. For medium category population density sector 9 and 15 are fitted but for 21 sector where maximum builtup areas for offices and recreation purposes was not fitted because of low dense population. For low population density all blocks are in acceptable category.
