There are always going to be slight variations when data is collected. If I asked a couple of people to find me the population of a town, one person may find a source that shows Heratunda has a population of 1,400 people and the other says there is 1,355 people.

The main point is that: different people are going to go to different sources in order to get the data.


(Heratunda is a made up place by the way)
