Mapping a Year in the Life of Boston

noreply@blogger.com (Jon Pollak) — Mon, 23 Jan 2012 19:14:00 +0000

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?

noreply@blogger.com (Jon Pollak) — Thu, 19 Jan 2012 20:36:00 +0000

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

noreply@blogger.com (UConn Libraries MAGIC and Connecticut State Data Center) — Wed, 18 Jan 2012 16:24:00 +0000

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/>.

Revisiting the Occupy Movement: Geographies of Protest

noreply@blogger.com (Jon Pollak) — Tue, 10 Jan 2012 14:10:00 +0000

As the Occupy Movement spread across the United States this fall, we here at Outside the Neatline documented some of the geospatially-related web content that was created in response to the protests. Recently, I came across an excellent geographic examination of the protests in a two part post on the Regional Geogblog entitled Geographies of Protest and Occupation: From Manama, Bahrain to Richmond, Virginia. The blog is maintained by Professor Donald Rallis from the Geography Department at the University of Mary Washington (my Alma mater!). In Part 1, Professor Rallis discusses the significance of occupation of a place as a form of protest in addition to the events of the Arab Spring in Bahrain while in Part 2 he focuses specifically on the Occupy Movement in the United States.

Click the map above to view interactive map

View Ratio of Income to Poverty Level for Families Data by Town in Connecticut

How can I access the 2006-2010 ACS 5 year estimates data?
The American FactFinder provides access to the 2006-2010 ACS 5 year estimates data for Connecticut as well as the entire nation. From the American FactFinder users can search datasets, download datasets, and create interactive maps based on variables from the ACS.

At what geographic levels is the data available?
The ACS 5 year data is available at the national, state, congressional district, county, county subdivision (town), tract, and block group level. For those users interested in examining block group level data the margin of error values could be significant at the block group level so be sure to review the margin of error values closely as tract level data may provide less error.

The Atlas of Economic Complexity

noreply@blogger.com (Jon Pollak) — Wed, 04 Jan 2012 20:00:00 +0000

The Atlas of Economic Complexity examines the connections of the global economy.

The Atlas of Economic Complexity: Mapping Paths to Prosperity is a fascinating look at the global economy. The Center for International Development at Harvard University, The Harvard Kennedy School, and Macro Connections at MIT have collaborated to create a project that includes both a detailed report and a dynamic set of interactive visualizations regarding countries' varying economic complexity. The report includes an economic complexity index ranking in which Japan ranks first (the US is ranked 13th).

A map of Economic Complexity Index rankings from the Atlas of Economic Complexity: Mapping Paths to Prosperity.

The aforementioned visualizations can be created at The Observatory of Economic Complexity, which allows you to generate a number of different economic charts and maps. For example, you can choose to show imports or exports, different products, and years. In addition, you can view charts as animations (from the years 1962-2009). Below are a few examples of these with the focus being on beer imports in the United States:

Brookings Maps Economic Recovery

noreply@blogger.com (Jon Pollak) — Fri, 16 Dec 2011 18:03:00 +0000

Yesterday, The Brookings Institution, a Washington, D.C. based nonprofit policy organization, released a report that classifies the economic recovery of the 100 largest metropolitan areas in the country through the third quarter of 2011. The report classified each metro area into 5 categories based on four indicators: employment change, unemployment rate change, gross metropolitan product change, and housing price index change. The full list of metro areas with their classification is available here, but Brookings has also created a very cool interactive map, which is symbolized by economic recovery. Additionally, clicking on one of the map's metro areas reveals an economic recovery report for the respective metro area.

According to the report, the strongest 20 metros are:

Albuquerque, NM
Bakersfield, CA
Boston-Cambridge-Quincy, MA-NH
Dallas-Fort Worth-Arlington, TX
Des Moines-West Des Moines, IA
Detroit-Warren-Livonia, MI
Grand Rapids-Wyoming, MI

Mother Jones Maps U.S. Crime Exonerations

noreply@blogger.com (Jon Pollak) — Thu, 15 Dec 2011 14:25:00 +0000

A new map from Mother Jones (pictured above) depicts 825 known crime exonerations in the United States since 1989. Clicking a state on the map allows you to find out specific information including the number of exonerations during this time period in the respective state as well as whether or not the exonerations were based on DNA evidence. For example, in Connecticut, the map indicates there have been 7 verified exonerations since 1989, 4 of which came via DNA evidence and 3 of them via non-DNA evidence. In addition, the map label indicates that Connecticut has a Compensation Law. The map also indicates the states where posthumous exonerations have occurred. Visit the Mother Jones article for more.

The Impact of High Speed Rail on Accessibility in China

noreply@blogger.com (Jon Pollak) — Mon, 12 Dec 2011 13:49:00 +0000

The planned National High Speed Rail Network in the People's Republic of China.

Jie Lin, who is a colleague of mine both at the CtSDC and the Department of Geography Ph.D. program, recently examined the impacts of the planned High Speed Rail Network in the People's Republic of China. Specifically, Jie's focus has been on the increase in accessibility that would be a result of implementing the planned high speed network. Before we dive into Jie's results, however, a little background.

The total area of China is comparable to the size of the United States and the majority of that land is continuous. China has varying local physical geography that can isolate places- like the mountainous region of Tibet. Consequently, the successful implementation of a transportation network with higher travel speeds and greater accessibility has consequences in the realms of culture, the economy, and the overall social fabric of the country. Greater accessibility means the spatiotemporal size of the country decreases (ie. it takes a shorter amount of time to go from A to B, thus making A and B "closer").

But, how does one calculate accessibility? Accessibility is defined by the ease of getting from place to place in a network. It is commonly calculated using a connectivity matrix like this:

This matrix is formed by counting how many nodes one must pass through in order to get to another node in the matrix. For example, the shortest way to go from A to E, is to pass through B, C, and E, so a 3 is added to Row A, Column E. The only difference in Jie's study is that the calculations are not based on how many nodes one must pass through, but rather the time (in hours) it takes via the shortest route. As you can see, this measure evaluates your ability to travel from each node to each and every other node in the network.

Jie's study, which included 31 provincial capitals and administered municipalities, was based on the following assumptions:

Speed of Normal Rail: 130 km/h
Speed of High Speed Rail: 280 km/h

Now, to Jie's results. The units, besides the percentage column, are in hours:

And, for those of you (like me) who prefer to communicate visually, here is the resulting map. Again, units are in hours:

One of the most interesting points that I discussed with Jie is that although there are no plans for the Tibetan Region to be served by high speed rail (it is served by normal rail), the accessibility of the city of Lhasa is increased tremendously due to the improvements in other parts of the network. In fact, Lhasa has the greatest absolute change in accessibility out of any city in the study. It will be interesting to see this will affect the region culturally, economically, and socially. Overall, Jie found that the full implementation of this high speed rail network would mean an average increase in accessibility of about 50% for the cities included in the study.

U.S. Census Bureau: More Families with Children Receive TANF During 2009 Recession

noreply@blogger.com (Jon Pollak) — Wed, 07 Dec 2011 14:16:00 +0000

The U.S. Census reports that families with children in the Temporary Assistance to Needy Families (TANF) increased from 3.8% in 2006 to 4.8% in 2009. TANF, a federal welfare program, was examined in a report entitled Comparing Program Participation of TANF and non-TANF Families Before and During a Time of Recession. The report's authors also imply that the impact of the Great Recession has not been limited to TANF and poor families. Click here to visit the U.S. Census Bureau's press released about this report.

Census Bureau Releases 2010 Income and Poverty Estimates for All Counties and School Districts

noreply@blogger.com (UConn Libraries MAGIC and Connecticut State Data Center) — Thu, 01 Dec 2011 18:48:00 +0000

Between 2007 and 2010, the poverty rate for school-age children showed a statistically significant increase in about 20 percent of counties across the United States, according to U.S. Census Bureau estimates for income and poverty in 2010 for every county and school district.

In all, 653 counties saw a significant increase in poverty for children ages 5 to 17 in families and eight counties saw a significant decrease over the period. A similar analysis of median household income showed 735 counties with a significant decrease over the 2007 to 2010 period and 78 counties with a significant increase.

The 2010 Small Area Income and Poverty Estimates (SAIPE) data are available for 3,142 counties and nearly 14,000 Title I-eligible school districts. The data represent the only current, single-year income and poverty estimates available for all sizes of counties and school districts. These estimates are released annually; however, 2007 was chosen for comparison because it was a pre-recessionary year.

The 2010 estimates also show that about one-third (1,011) of counties had school-age poverty rates significantly above the national poverty rate of 19.8 percent and 851 counties had rates significantly below. Among the 1,306 counties with total population less than 20,000, 73 counties were significantly above 30 percent poverty for school-age children in 2010. There were 48 counties above 30 percent in 2007.

“SAIPE also provides county and state estimates for the total number of people in poverty, the number of children under 5 in poverty (for states only), the number of children 5 to 17 in families in poverty, the number of children under 18 in poverty and median household income. School district estimates from SAIPE, produced for the Department of Education to implement provisions of the No Child Left Behind Act of 2001, are available for the total population, the number of children 5 to 17 and the number of children 5 to 17 in families in poverty.

“This release includes publication of the 2010 SAIPE Highlights Document, which presents SAIPE statistical trends and explains the sources and approach. Also available is an interactive mapping tool (http://www.census.gov/did/www/saipe/data/maps/index.html), allowing access to the county and school district statistics by selecting the geographic area for display, as well as thematic maps for all concepts available from SAIPE 2010 and 2009. More information can be obtained from the SAIPE main page.

SAIPE combines the latest American Community Survey data with aggregate data from federal tax information, administrative records on Supplemental Nutrition Assistance Program participation, 2000 and 2010 Census statistics and annual population estimates.

These statistics, sponsored by the U.S. Department of Education, are used as one of the criteria to allocate federal funds to local educational agencies. In addition, state and local programs use these statistics for distributing funds and managing school programs.

Modeling the Elevation of Martha's Vineyard in ArcGIS

noreply@blogger.com (Jon Pollak) — Wed, 30 Nov 2011 18:39:00 +0000

This year, my graduate research in the UConn Department of Geography has focused on the vulnerability of Martha's Vineyard to climate-related hazards like sea level rise and hurricanes. Using ArcGIS' 3D Analyst, I have created a triangulated irregular network (TIN) to visualize elevation, which you can see above. I generated this model from contour lines (3 meter intervals), which I downloaded from MassGIS. Those of you familiar with the island will notice that this data, from 2005, does not show the breach of Norton Point Beach, which occurred most recently in 2007. For climate related happenings in the Cape Cod and Islands region, check out Climatide- a blog from the Cape and Islands NPR station (WCAI) and authored by Dr. Heather Goldstone.

Special Tabulation Based on Supplemental Poverty Measure Update

noreply@blogger.com (UConn Libraries MAGIC and Connecticut State Data Center) — Fri, 25 Nov 2011 18:18:00 +0000

In a follow-up to the release of the supplemental poverty measure report, the New York Times commissioned the Census Bureau to create a special tabulation based on the measure, and as a service to other users we are posting this tabulation online. The statistics focus on the characteristics of the population just above the poverty line (100 to 150 percent of the poverty threshold). The supplemental poverty measure does not replace the official poverty measure but is intended to better reflect contemporary social and economic realities and government policy effects and thus provide a further understanding of economic conditions and trends.

Tracking Migration Patterns in the U.S.

noreply@blogger.com (Jon Pollak) — Fri, 18 Nov 2011 20:21:00 +0000

Migration patterns of Tolland County, CT from this Forbes interactive map.

Are you interested in migration patterns in the U.S.? If so, check out this interactive map from Forbes, which is based on IRS data. The map details in and out migration by county. As an example, see the screenshot above of Tolland County, CT. It shows that between 2005-2009, 7,400 people migrated to Tolland County while 3,700 migrated away from Tolland County. The map also allows you to track where the in-migrants are coming from and where the out-migrants are going.
