Population density is the number of people living per square kilometer in an area. Population distribution on the other hand is the measure of just how much people are spread in a particular area. When referring to the way a selected population is dispersed in a particular geographical area, population distribution comes into play while population density is more about the number of people per unit area. More people tend to live in urban areas than in rural areas. For example, the population of the Yukon-Koyukuk census area in central Alaska stands at just 5,377, a very low value when compared to New York’s 8.419 million. The former has an area of 145,505 square miles while that of the latter is 302. 6 square miles. With this, New York has a larger population density than Yukon-Koyukuk and there is more distribution of people in New York than in Yukon-Koyukuk.
