A new Google Maps mashup on the CtSDC website displays historical centers of population in Connecticut (1880-2010).

Back in October, we posted the latitude and longitudes of  the historical centers of population for Connecticut based upon decennial census data from 1880 to 2010. We have added this data to a new Google Maps mashup that can be viewed on the Connecticut State Data Center website. As of the 2010 Census, the population center of Connecticut is near Andrea Court and Yalesville Road in Cheshire. Special thanks to Daniel Czaja for formatting and processing the data!

Is it a Map or a Chart?

I’m starting a new adventure and it all came about from playing around with maps!  Last month I was hired as the supervisor of the Treworgy Planetarium at Mystic Seaport and that means you’ll probably be hearing less and less from me as an author here at Outside the Neatline.  You may be hearing about special events or items of interest that I stumble across or new geographical information related to the maritime tradition.  For example, do you know what the difference between a map and a chart?  I’ve had to learn quickly!

Reading and using a chart is one of the basic skills that are taught at the Treworgy Planetarium.  Concepts such as map projections, scale, taking bearings and plotting headings are covered in the classwork (very geographical).  Other course offerings include taking a noon sighting of the sun with a sextant, celestial navigation to find latitude and longitude, and marine weather.

In the next few months I’ll be developing a new blog platform for the Treworgy Planetarium so keep your eyes peeled!

Washington, D.C.: Then and Now

For a look into the past of Washington, D.C., check out the The Ruined Capitol Blog:

A photo depository and discussion dedicated to the comparison of buildings, culture, and society in Washington, D.C. that have been destroyed, replaced or miraculously preserved during the great architectural purge of the Federal City from 1930 to the 1980s.


This blog features historical photos from locations in the nation’s capitol that show the evolution of its urban geography. It’s amazing to see some of these older photographs compared to their contemporary counterparts for a variety of reasons, but one is the difference in scale. An example of this can be seen in the two photographs below, at the intersection of K and 15th St NW (dated ca. 1922; Present). With wider roads and taller buildings, as the author notes, the urban design and architecture have given this location a tremendously different scale and sense of place.

The Research and Innovative Technology Administration of the U.S. Department of Transportation has released an interactive application, entitled State Transportation Facts and Figures, that allows you to explore transportation statistics by state. The statistics included fall under 7 categories:

  • Infrastructure
  • Fatalities and Injuries
  • Distracted Driving 
  • Freight Transportation
  • Passenger Travel
  • Economy and Finance
  • Energy and Environment

The data can be viewed as a map, bar chart, pie chart, or scatter chart, or, by clicking the various drop down menus of the application, you have the option of downloading the source data in addition to printing the various figures.

Mapping a Year in the Life of Boston

At the end of December, The Boston Globe ran this geographic narrative that mapped 17 events of 2011 in the city of Boston. Here are a few of my favorites:

  • 8. The puck stopped here – In June, the Bruins won their first Stanley Cup since 1972. Their victory sparked riots in Vancouver, home of their opponents. At home, the win was celebrated with a victory parade through downtown Boston.
  • 11. Whitey’s back – After 16 years on the lam, infamous South Boston gangster Whitey Bulger was captured in Santa Monica, Calif., and arraigned at Boston’s federal courthouse.
  • 12. Occupied! – The encampment in Dewey Square was one of the longest-lasting of the Occupy protests in major US cities. Protesters began the demonstration on Sept. 30; on Dec. 10, the camp was cleared by police, resulting in dozens of arrests.

A Geographic Look at the Proposed Keystone XL Pipeline: Where Does Tar Sands Oil Get Refined?

Posted on by

In the United States, the answer is a whole bunch of places (excluding the Eastern Seaboard). In the wake of President Obama’s rejection of TransCanada’s proposed route of the Keystone XL Pipeline, check out this map of refineries in the US that handle tar sands oil (pictured above; source: Mother Jones). As you can see, there are nearly 50 refineries who handle tar sands oil in the country. Besides furthering a seemingly never ending addiction to fossil fuels that will continue to change our climate, an important item that has been glossed over by many reporting on this decision in regards to energy security is the fact that the proposed pipeline would have ended in the Gulf Coast region. From a geographic point of view, this route can be interpreted as a clear signal that the pipeline’s intended purpose is to maximize the ability to export the refined products and maximize corporate profits, without necessarily being the dependable source of domestic energy that some have touted it to be. In fact, according to the TransCanada website, a newly built pipeline from Alberta to Illinois already exists and is in service as you can see in the map below.

With this decision by the Obama Administration, TransCanada is believed to be moving ahead on an alternative route.

Census Bureau Releases New Race and Ethnic Demographic Information from the 2010 Census for Connecticut

The U.S. Census Bureau on Thursday January 12, 2012 released new, detailed demographic information from the 2010 Census for up to 331 different race and ethnic groups down to the census tract level for Connecticut.

These Summary File 2 tables add a new layer of detail to the population and housing topics released last year from the 2010 Census. Information, such as age, relationship and homeownership, previously available only for an area’s entire population is now available for specific race and ethnic groups in that community.
Each Summary File 2 table is presented for up to 331 population groups. These include iteration groups for the total population, race alone groups, race alone or in combination groups, multiple-race combinations, American Indian and Alaska Native tribal groupings, detailed Asian groups, detailed Native Hawaiian and Other Pacific Islander groups, detailed Hispanic groups, and race/Hispanic groups.

Geographies Available

The statistics are available for a variety of geographic areas: counties, county subdivisions, places, census tracts, ZIP Code tabulation areas, congressional districts for the 111th Congress, American Indian and Alaska Native areas within the states released, tribal subdivisions, metropolitan areas and Hawaiian home lands.
To preserve confidentiality, only geographic entities with a population of at least 100 for the specified group are available in the summary file.

 

Accessing the Information

During the embargo period, the Summary File 2 tables can be found on the Census Bureau’s American FactFinder website at <http://factfinder2.census.gov> by using the “Population Groups” filter to select the specific race or ethnic groups of interest. While a variety of tables will be available, a good place to start is the Profile of General Population and Housing Characteristics, which shows a summary of characteristics for one geographic area at a time.

A summary file version of the information is also available for users who want to download the set of detailed tables for all of the geographies within a state and run their own analysis and rankings. The summary file contains two parts: a file with the geographic headers (in fixed-length ASCII format) and a file with the statistical information (in comma-separated ASCII format). The summary file is available for download at <http://www2.census.gov/census_2010/05-Summary_File_2/>.
