Land use types are divided according to the difference of population density. The concrete method of this method is: to interpret the aerial photos, first distinguish between residence and non-residence, then distinguish various types of houses in the residence, and draw the boundaries of various types of houses. Then calculate the area of various residential land, multiply the area of various residential types with the average population density of the corresponding residential types in the sampling block, and then get the estimated population of various residential types. The sum of the estimated population of each housing type is the total population of the whole region.
