Proportional Circles Map

Choropleth Maps

percent_of change_division.ai

I separated the excel file into divisions by adding a column ‘division’. I then performed the calculations to obtain the percent of increase per division, copied the totals into a second file and opened it in ArcMap. I performed a join using the division column and revised the map to Equal interval using the division column. I selected a black to white color range and saved the new map as an .ai file. I moved the scale bar into the layer with the map and put the subtitle and north arrow in each layer containing the frame. I adjusted the grays and placed heavier boarders around the states that were shaded light to give them more definition, and saved the map.

percent_of_change.ai

I separated the three areas into separate layers and sized the windows around the subject area. I then changed the projection for each layer to display the map in the proper proportions. The state_pop,shp file is in GCS North American 1983 CSRS. For the lower forty eight states I used the North American Albers Equal Area Conic projection. The Alaska frame is in NAD 1983 Alaska Albers and the Hawaii frame is in the same projection as the shape file. Changing it did not seem to make much difference in the appearance. In ‘AI’ all the features associated with a frame where moved to the group containing the map group. I renamed the layers to identify the contents and saved the map.
