GIS Maps (5/17/2006)

Prevention Center of Excellence, Center for Community Inclusion and Disability Studies

Maps 1-3 provide a visual picture of binary relationships within geographic locations in Maine among the following variables:

  1. Population density
  2. Prevention infrastructure coverage

Prevention infrastructure data were obtained through telephone interview and web information collected by PCOE staff from October 13, 2005- October 25, 2005.

Map #1 illustrates prevention infrastructure as depicted by the number of core programs in each geographic area. This map depicts programs by minor civil divisions and thus does not present data at the smallest level of census measurement. The key depicts the meaning of shapes, color scheme and lines. Towns and cities are included for geographic orientation only.

Map #2 provides a visual image of the relationship between core program prevention infrastructure coverage and population density. This map depicts programs and population density by minor civil divisions and thus does not present data at the smallest level of census measurement. The key depicts the meaning of shapes, color scheme and lines. Towns and cities are included for geographic orientation only.

Map #3 presents prevention infrastructure coverage by minor civil division {as measured by the number of total programs (0-7)}, and population density by block group. As noted in the definitions below, census blocks are the smallest level of measurement, and thus population density is depicted in this map differently than in Map #2. Programs are noted by number rather than color for clarity of viewing the relationship between population and infrastructure coverage. The key depicts the meaning of shapes, color scheme and lines. Towns and cities are included for geographic orientation only.

Definitions

Census blocks: the smallest geographic area for which the Bureau of the Census collects and tabulates decennial census data, formed by streets, roads, railroads, streams and other bodies of water, other visible physical and cultural features, and the legal boundaries shown on Census Bureau maps. (www.census.gov/geo/www/GARM/Ch11GARM.pdf)

Valid percentage; the percentage of the total number of respondents for each item.(Depoy, E. and Gitlin, L. ( 2005) Introduction to research. St Louis, MO: Mosby.)

Minor civil divisions: the primary political or administrative divisions of a county. MCDs represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions. MCDs include, among others, American Indian reservations, assessment districts, boroughs, precincts, towns, and townships. (www.library.wisc.edu/guides/govdocs/census/geog.htm)
