Columbia Demographics 1990-2009 – Useful Eye Candy

To help better understand demographic change, I have taken the time to put together a map that helps depict the changes in Columbia, MD.  Shown below is a map of most of Columbia.  My apologies to the folks in Dorsey’s Search north of MD 108, the US Census boundaries in your area do not match up easily, and it would take me weeks to put together the numbers in your neighborhood.

For the remainder of Columbia, I have outlined the year 2000 Census Tracts that comprise the city.  If you click on a section of the map, it will display the name of the neighborhood and the total population for that area in 1990, 2000, and 2009 (estimate).  In addition, each pop-up window includes the statement “click here for details.”  I encourage everyone to “click here.”  By doing so, it will direct you to a spreadsheet that displays the detailed demographic data for the geographic area and in many parts of the city, it tells an interesting story.  For instance, the Columbia Association is concerned about the decline of those 21-54 years old in Columbia.  In the Hopewell neighborhood, this age group has seen a 40% drop (estimated), but attendance at the Hopewell pool is one of the best in the city.  This is just one example of the dynamic changes occurring throughout the city over the last twenty years.

It is important to note here that the 2009 data is an estimate, and at times carries a large margin of error.  The US Census Bureau is releasing state 2010 Census demographic data throughout this month.  When the new 2010 data becomes available, I will update the map and spreadsheets.

Also, in the lower left corner of each spreadsheet, shaded in blue, the limited data from the 2010 Census can be found.  I encourage you to look at it.  In many cases, the 2010 Census data does not correlate with the 2009 estimates. 

Coming up soon:  Let’s look at CA Aquatics Pool Attendance Data!
