Analyzing population by ward

Every ten years the U.S. Census Bureau conducts a survey in order to
find out how many people are living in a specific area among other
things. Once completed with the survey, they then eventually release
this information to the public. The ability to access this data from the
Census Bureau as well as its use to answer important questions is at
times invaluable. For the City of Park Ridge, they decided to use the
Geographic Information System (GIS) as there catalyst for first
accessing this information from the Census Bureau and second, to
determine how many people are living within each municipal election
ward.

Based on information from the City Clerk, each election ward within
the city requires a minimum population count of 5,000 people. This
number ensures that each ward is properly divided in terms of population
allowing equal representation for all residents who reside within the
city. If the population counts fall below this number, the ward
boundaries will be reviewed and adjusted in GIS if needed in an effort
to equalize these numbers. Although the current Census Bureau population
totals are based on numbers from the year 2000, reviewing the ward
boundaries before the 2010 Census survey gave the City Clerk and the GIS
Department an understanding of how to analyze this data. Now that this
methodology has been uncovered, GIS can easily perform this task when
the 2010 data is released. Thus demonstrating how GIS can easily access
Census Bureau information and compare it with local election ward data
in order to plan for the possibility of future ward boundary
adjustments.
