Population estimation for child care centers through linear regressions

This article arises as an alternative solution to the problem of estimating the future population of some care centers for children and adolescents at social risk. The population of these centers fluctuates from month to month due to various social, economic and political factors, so there is no way to calculate exactly how many children will enter and how many will leave. To make the estimate, a mathematical model was developed to estimate the population of the centers in the following month based on linear regressions and it was implemented in a spreadsheet to facilitate its use.
