The program currently, as outlined, calculates the growth rate of whatever population  data I input into it.  It organizes the csv file into a hashtable, and later a hashtable matrix in order to use simple calls such as [VA][1840] to obtain the specific data required.  The program then uses the hashtables and the Verhulst equation to calculate the rate of growth.
