Native Connecticut Residents with Bachelor’s, Graduate, or Professional Degrees

By: Heather Ewry

In the state of Connecticut, the number of people born in-state who went on to get a bachelor’s, graduate, or professional degree made up a sizable fraction of the people who possessed one of those degrees during the years 2012 and 2013, though they made up a much smaller percentage of the Connecticut population as a whole. In 2012, these people were approximately 77% of the state’s degree holders fell within this category while making up just 14% of the state’s total population. In 2013, both of these percentages increased: now, native Connecticut residents with bachelor’s, graduate, or professional degrees made up 78% of its degree holders while making up approximately 15% of the entire population within the state.

The provided tables and charts break these percentages down by county and year. Interestingly, though the total percentage for the state went up, the county breakdown reveals that this increase was not necessarily reflected by the individual counties. Middlesex County, for example, saw a 3% increase in the number of native Connecticut residents who possessed bachelor’s degrees but a 1% decrease in the number native Connecticut residents who possessed graduate or professional degrees instead. Windham County, on the other hand, saw a 4% increase in the number of native Connecticut residents with bachelor’s degrees as well as a 1% increase in those with graduate or professional degrees.

American Community Survey Workers from Home, 2010-2013

Author: Zachary Guarino

Introduction: This project focuses on comparing the annual percentage of workers at home for primarily the State of Connecticut in comparison to the United States National average from the years 2010 to 2013.

Data: The data is derived from the American Community Survey Means of Transportation to Work by Age 1-Year Estimates from 2010 to 2013. The age breakdowns were aggregated together for this analysis because the focus in on the average for the State and not each age grouping. The workers at home percentage was calculated by dividing the number of workers at home by the total number of workers. Utilizing Tableau software I was able to create visualizations for this data set. There is a wide range of interactive visualizations including line and bar graphs. Most of the Dashboard space is used to show comparisons withe Connecticut and the U.S. workers at home percentage, but I went t a step further to also show how Connecticut compared to other states in New England. Several features on the Dashboard can be altered according to a specific year of interest, allowing for closer comparison in a given year. The trend lines also tell a story of how many workers at home there are over the 3 year span of 2010 to 2013.

Findings: Through the data visualizations I was able to come to the conclusion that Connecticut has had an increase in people who work from home, increasing about 0.39% from 2010 to 2013. There was a slight drop in 2012 but the overall trend is increasing. The percentage of people working at home for the National average had a much more gradual trend line, only increasing by 0.03% from 2010 to 2013. Connecticut has never been higher then the National average yet but is approaching closer every year. In 2013, Connecticut was at 4.33% workers from home the National average only was slightly higher at 4.36%. In comparison to New England, Connecticut although not having the highest percentage of workings at home ranks pretty well given its increasing trend. States like New Hampshire and Rhode Island appear to be on a decrease in people working at home. Vermont’s percentage has been fluctuating a lot, however Connecticut, Maine, and Massachusetts all have positive slopes. A closer look at the trend line shows that Maine has the greatest increase, followed by Connecticut and Massachusetts. So I would rank Connecticut 2nd in percentage of workers at home in New England. The visualization for New England on the Dashboard has a year by year comparison bar graph to allow for analysis at the annual level and the line graphs have been omitted for conservation of space.


Means of Transportation to Work by Age, American Community Survey 1-Year Estimates, 2010 – 2013

2013 Estimates:|0100000US.04000

2012 Estimates:|0100000US.04000

Household Income Quintiles and the Top 5%

The above map, based on table B19080: “Household income quintile upper limits”  from the 2013 American Community Survey, displays income amounts which would put a household among the wealthiest 5% in their state. The stacked bars adjacent to the map display household income distribution within a state by quintiles, providing an overview of household income distribution.

For Connecticut, New Jersey, and District of Columbia, table B19080 from the 2013 ACS reports that the top 5% of households by income have lower income limits of “250,000+”, while more precise estimates are provided for all other states. Connecticut reached this apparent “250,000+” reporting ceiling in the 2011 American Community Survey report. The top 5% of households in District of Columbia surpassed this threshold several years earlier. Interestingly, in 2009 the American Community Survey reported that the lower limit of the top 5% of households in D.C. was $279,845; in this year’s report the figure is reported simply as being “$250,000+”, obscuring the true estimate. Table B19083 from the 2013 ACS indicates that the District of Columbia has a greater level of income inequality than any state; New York and Connecticut have the highest Gini index among states.


New data from American Community Survey for Connecticut towns

The American Community Survey 2009-13 ACS 5-Year dataset, released today by the U.S. Census Bureau, provides new economic and demographic data for smaller geographic areas including all 169 Connecticut towns. The visualization below provides a snapshot of just a few measures from one report within this dataset, “DP03 – Selected Economic Characteristics” – just one of the more than 2,000 tables of new data for Connecticut towns, Congressional districts, school districts, Census Tracts, and other areas. To browse for more detailed economic data on any town, follow the link that appears when you hover over any map in the visualization – or start browsing American FactFinder with some of the links below:


Highlighting CT Open Data: Hartford Fire Incidents

The Connecticut State Data Center has recently been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.

This fifth visualization takes a look at incidents reported to the Hartford Fire Department between January 1st and November 19th. There are four views; three are maps, and the other is an area chart that shows incidents over time broken down by zip code. Note that not all of these incidents necessarily involve a fire. When clicking on a point in the map, there is a link to a PDF with explanation of all the incident codes.  You can see all of the original data here.

Just like other visualizations, this story also includes a GoogleMaps interface so you can look at incident locations using a satellite basemap or Google Street View.

Highlighting CT Open Data: Certified Organic Growers

The Connecticut State Data Center has recently been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.

This fourth visualization is a simple look at USDA-certified organic growers across the State of Connecticut. The map allows you to filter based on the county where the growers are located or by the body that provided their certification. Further, there’s a wildcard match bar that allows you to search for specific kinds of produce and goods and see which growers are specializing in those products. You can see the original data here.

Highlighting CT Open Data: Brownfield Remediation Assistance

The Connecticut State Data Center has been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.

This third visualization uses data to provide an overview of brownfield remediation around the state, focusing in particular on projects that have received funding assistance from different government sources. In all, there are 173 financially-assisted remediation projects featured since 2005. You can see the original data here.

Using this visualization allows you to see what projects are happening where, who’s funding those projects, and how much land is being reclaimed and for how much. One page provides an interactive pie chart that can be filtered by municipality and span of time, allowing for comparison of funding sources in different periods and places. One map focuses on remediation assistance applicants; the filters on this map allow for viewing certain projects based on applicant municipality or applicant name. As with previous visualizations, there’s also a GoogleMaps interface that allows for seeing the remediation sites with a satellite basemap and Google Street View.

Highlighting CT Open Data: Hartford Planning Applications

The Connecticut State Data Center has been working on visualizations that highlight some of the data available on the Connecticut Open Data Portal.

This second visualization is a look at planning applications submitted to the City of Hartford between June 30th, 2009 and November 10th, 2014. The original data can be found here.

This visualization includes three views. The first is a map that can be easily searched by street name or filtered by date of application and application type. The second view is a GoogleMaps interface that allows a user to view the data over satellite imagery and even use Google Street View to try and see specific properties. In addition, there is an interactive area chart that tracks the total number of applications submitted per year, including those totals broken down by the type of application.
