. Also, an exploration of data on the distribution of population inside principal cities versus other incorporated places could provide additional insights on the extent of political fragmentation within each metropolitan or micropolitan statistical area. Finally, a statistical exploration (e.g., regression analysis) of the potentially explanatory relationship between the number of governmental units, the percent of population in unincorporated areas, and conditions associated with urban sprawl may prove interesting, provided an acceptable quantitative measure of sprawl can be reached.
