In the same respect, the county may change from rural to urban, even if there is population loss in the county, as in Kimball County. An example of this would be Cass County. The purpose of this project is to point out the factors that may influence change in rural and urban populations and where these changes occur. Methodology Much of the data for this project was acquired from library census data and data on the internet. After obtaining the data, it was then compiled into an excel spreadsheet and joined to the shapefile database.
All choropleth maps use natural breaks for statistical characterization.
To produce any map for Nebraska, all records not pertaining to Nebraska had to be deleted. All completed maps were exported in JPEG format to my directory. To produce the a choropleth map of population change between 1950 and 1990, information on census data needed to be extracted from Esridata in the ArcView database and data in text form from census material located in the library needed inputed. The data is not immediately current as the 2000 census data, but it serves its purpose in showing the differentiation between the data. Using Excel for inputting the data , it was necessary to calculate the percent of population change between the two years.
