Let's look for trends in population change in the Lehigh
Valley watershed from 1990 to 2000 using a GIS map.
- First, look at the "percentage change from
1990 - 2000" map color. Remember to view the legend to
access the color key. What patterns do you see on this map? What regions
of the watershed appear to be substantially increasing in population?
What areas are not growing as fast?
- Use the information tool to look for changes in
the population in the city centers (Allentown, Easton, and Bethlehem)
and the cities, towns, and other municipalities that surround them.
Do you notice any trends? If so, what do you think is causing these
trends? If you do not see any evident trends, how might you explain
this?
