This map was created in Adobe Illustrator from a copy of the Population change by state map. I had selected a gray scale from the swatches layers in AI before I read the instruction about using the edit color command and choosing gray scale. The way I used the gray scale was more difficult but had the same end result. I chose to label the divisions to clarify the four divisions from North Central to New England.
The challenge for this project was manipulating the data for the percentage of change and class breaks in Excel. It wasn't difficult just very time consuming creating the Census Divisions from the list of states. The data is broken down using equal interval classes. Equal interval is a poor choice for this data because it leaves one interval class unused and lumps four other division that are colocated into one class. I wasn't sure how much liberty to take on decimal points in the percentages. I wanted to use two decimal points but would have ended up with a duplicate to and from number so I ended up with two and three decimal points.
I learned from the reading to not have any spaces between the color blocks in the legend. I'm curious if ArcMap gives that option in the legend styles.
Nice job Lynn.
