The buffer boundary is represented below by the red ring.
The appropriate counties are highlighted below in green.
197 counties completely within the buffer 220 counties whose centroid is in the buffer 242 counties that intersect the buffer



QUESTION 5
How many individual US Counties have a larger area than the whole state of Delaware?



The counties that have a larger area than the whole state of Delaware are highlighted below in green.

There are 279 counties in the US that have a larger area then the whole state of Delaware.


QUESTION 6

What was the overall percent population growth in these counties between 1990 and 2000?
What was the overall percent population growth in the counties not intersected
by an interstate or equivalent highway?

There are 1,772 counties not intersected by an interstate or equivalent highway. The population grew between 1990 and 2000 in these counties by 11.9%.



Graduated Colors Thematic maps of White, Black and Hispanic populations normalized by the population in 2000.
The Quantiles method is the truest-looking geographic distributions.

Below is a map of the portion of the states that are located within 200 miles of
New Castle County. The proportion of the states is labeled for each state.




Cartographic Map



Thematic map, Elderly normalized by the population in 2000



Map of the true percentage of elderly by state.

Note: The true percentages of elderly by state are inconsistent with the percentages of elderly by county because
within the county layer, two counties with zero elderly population were discluded which caused discrepencies in the data.



By joining the table attributes of the Summarize table and the States layer, and then creating a Percent Black
field in the States layer, after the Summarize table join is removed, the Percent Black field remains in the State's layer.

The Map of Percent Blacks by State can be seen below.



The percent change from 1990 to 2000 of the 12 Northeast States (selected below in pink) can be seen in the bar chart below.
