POPDENS - Population density

Population density was calculated by summing number of people living in the 1 km grid cell reporting unit and dividing by the grid cell area. Where census units were not completely contained within the grid cell, population was apportioned by area. High population densities are generally well correlated with high amounts of human land uses, especially urban and residential development. Large areas of development often involve substantial modification of natural vegetation cover and may have significant effects on wildlife habitat, soil erosion and water quality.
