Maryland

Map 1


This map shows the locations of Maryland’s landfills mapped against locations of Maryland’s public schools in 2007-2008. The darker green dots indicate the public schools with over 1000 students. This map highlights the high amount of landfills that are found close to the public schools in the state, especially in the central area of Maryland.

This map shows the locations of Maryland’s landfills mapped against the percent poverty of the area. The percent poverty of the area by county data are from 2008. Out of the 26 landfills found in Maryland, 5 of them are sited in areas with more than 18% poverty rates.

This map shows the locations of Maryland’s landfills mapped against the resident population by county in 2003. The population data are from the Census Bureau's annual midyear population estimate. Intriguingly, there is only one landfill in the most populated areas of Maryland. 5 out of 26 of the landfills are sited in the least populated areas of Maryland.

This map shows the locations of Maryland’s landfills mapped against amount of African-American births by county. The amount of African-American births by county data are from the Department of Health and Mental Hygiene from 2005. Interesting, there are more landfills and recorded African-American births in the center of the state. Out of the 26 landfills found in Maryland, 5 of them are sited in areas with more than 1,000 African-American births per year.

This map shows the locations of Maryland’s landfills mapped against the average wage per job by county in Maryland. Interestingly, out of the 26 landfills found in Maryland, 6 of them are sited in areas where the average wages per job by county are between $32,340 and $35,132.


Pennsylvania

Map 1



This map shows the population by county of Pennsylvania. It is separated by 5 categories of population density, from lightest to darkest. The red dots represent landfill locations. The interesting part about the map is how the landfills are concentrated in the more populated counties. The areas around Pittsburgh and Philadelphia are the most populous regions, with a high concentration of landfills in the immediate and surrounding counties. The mid-southern, mid-central, and mid-northern areas, along with the NE and NW region, all have the lowest population concentrations in their counties. There are few landfills in these regions.

The map shows the median home value by county. The home values have 5 spectrum's of green. PA only contains counties with the middle three of the spectrum, leaving out high end or low end possibilities. The landfills are mostly located in the middle shade of green.

This map shows public school in Pennsylvania, represented on a white to green dot scale. The greener the dot, the heavier the concentration of African American students in the school. The red dots represent landfills in the state. The map seems to have landfills around the green concentrations. This is especially true in the NW, SW, and SE corners. But this is a small coincidence, and there are far more landfills around the white dots.

This map breaks shows personal income levels by county in Pennsylvania. The light counties have the lowest income and the dark counties have the highest. The red dots represent landfill locations. This map shows that most landfills are concentrated in the counties with higher personal income levels. This can be seen in the SW Pittsburgh region, the SE Philadelphia region, and the south-central groups of counties.

This map shows the state of PA broken up by the per capita number of jobs per county. The light counties have the least jobs, the dark counties have the most. The red dots represent landfills. There is a pretty fair distribution of landfills across counties. The map seems to indicate that the number of jobs in the county does not influence/was not influenced by the number of landfills in that county.
