I'm looking for input on how best to evaluate a potential relationship between the presence of a particular type of facility in census district polygons and the population change in those districts. I have a series of population totals by district over many years while the facilities were being built throughout the area, as well as the location of and year each facility was built.
By the end of the time series the facilities go from being present in 1% of the districts to around 26% of them and I'd like to evaluate how the population change in those districts compares to others in the area and if the facility presence may be related to population change. I feel like there may be a number of ways to approach this and am not certain how best to get started on it.
Any suggestions are appreciated!
