It estimates the number of people per 30 arc-second grid cell (approximately 1km) using census and population registers. The `population_count` band represents the estimated number of persons per grid cell, with a pixel size of 927.67 meters. Data is distributed proportionally from census units, extrapolated for modeled years. The data should be calculated at its native resolution due to the data model.\n"]]
