This map was made as a continuation of the previous map entitled "Mexico's Population". Similarly,  the layers mex_rails, mex_rivers, mex_roads, and mex_urban were dragged from ArcCatalog into ArcMap and Mex_states was unchecked (turned off). The layers were then organize to the best of my ability to ensure that all were visible since they appeared too cluttered initially. To help with this problem, the symbology of the layers were altered to show only some of the feature categories to make the map more readable. For example. this was done by right clicking on mex_rivers layer and select properties. Symbology Properties were changed based on Categories and Unique Values. Primary and Major was then chosen under displayed value field, "RANK". Primary are symbolized as a dark blue colored line with a 1 line width and Major with the same width and a slightly lighter shade of blue. A similar procedure was done the the other 3 layers listed above. Next, it was determined with an SQL query, through the labeling properties for the mex_urban layer, that only areas with a population over 1,000,000 would be represented on the map. Next, the labels of each state were converted to annotations in order to manipulate each on its own. In particular, the label for “Districto Federal” was changed to "Mexico City" with a font size of about 22 and emboldened text. The text of the other states were changed to a size 14 emboldened font. The labels for World_countries layer was converted to annotations as well and the size of the “Mexico” label was increased. Next, an inset map was created to show the location of Mexico in the Central American Region. Lastly, map features were then rearranged to suit the map display and the title was changed to "Central Mexico". The map was then saved and exported as a jpeg file as shown above.
