Healthy American States & NYC Marathon 2011

posted Mar 2, 2012, 7:58 PM by M Srini

Reports after reports comment on how obesity threatens the future of America.  The last report paints a rather grim picture with only one state, Colorado reporting < 20% adult obesity rates.  Looking at the positive side, one could deduce that Colorado is the healthiest state in the USA.

A few months ago after running my 2nd NYC Marathon (2011), I thought it would be a good exercise to check the contribution of each of the states to this mega event (or Runner's Christmas as one of my friend calls it).  How many runners did each of these states send per million of its population?  This I thought should give a good estimate of the healthiness of the respective states.  As expected, Colorado romps home with one of the highest NYC Marathon runners per Million population.

The patch of states in the south from OK, LA, AL, MS, AR, TN, KY & WV form the belt with the lowest participation rates in the country.  It is interesting how the density map mirrors almost exactly that of the obesity rates from 2010 (Orange colored states in the image on the right).

NYC Marathon Participation

It should be noted that I've assumed that the traveling expenses remain uniform across different states (which is not true!).  This also explains why I've selectively removed states like NY, NJ, CT, MA from consideration (VT as well though it is still in the map on the left).  These neighboring states also have the advantage of NYRR's 9+1 program where one can gain eligibility to run the marathon by running 9 local races & volunteering for one.

The raw data is here if you want to play with it.  The NYC Marathon data was collected from finisher stats here.  US Population data is from Census 2010.

Patent of the week

A couple of weeks ago I received this mail from my graduate school Adviser, pointing to an article from Long Island Business News.  This article was titled 'patent of the week: large scale sentiment analysis'.  I, for once LOL'ed :-)  Yes, in spite of that being my master's thesis.  The reasons are two fold.  One, my thoughts & views on patents have changed.  Two, how does such a website decide what is the patent of the week?  I'm a bit curious.  In any case, I can add this to my resume as an invention.

Population of Indian States compared to Countries

Inspired by this economist map, here is an attempt at finding countries (UNDP 2009) that are similar in population to various Indian states (Census 2011).  Hover your mouse over your favorite Indian state on the map to get its equivalent country.  A couple of highlights:-

Looking at some of World's troubled countries and their Indian counter parts - Egypt (Andhra Pradesh), Tunisia (Uttarakhand) and Iraq (Assam).  These Indian provinces  are currently undergoing similar turmoil (except for Uttarakhand) with Telangana movement in AP & insurgency in Assam.  Uttarakhand in the past went through a similar phase before attaining statehood.  And yet, we are still one country.  It is a miracle!

Literacy Rate of Indian States - 2011 Census

The provisional Indian census data for 2011 is now out.  As a data nerd, I couldn't but visualize this data.  Overall, the literacy rate for India jumped to 74.4% which is good.  Here is a map visualizing data by states & union territories.  As you can see, Kerala & Mizoram take the top honours with over 90% literacy.  My home state Karnataka does a bit above national average at 75.60%.  The slackers Bihar, Arunachal Pradesh, Rajasthan, Jharkhand & Andhra Pradesh (AP) have literacy rates below 70%.  Hope Nitish Babu is listening!  I was surprised to see AP doing so bad though.

Physical Inactivity in NYC

posted Mar 21, 2011, 7:48 PM by M Srini   [ updated Mar 21, 2011, 8:52 PM ]

Almost a month ago, there was this article from usa today that I chanced upon.  This was a summary of the report by Center for Disease Control and Prevention that looked at the level of physical inactivity from county to county in the US.  The report found that the counties in the South were the least active.  Colorado with its mountains (and open space) was the most.  Less surprise here.

Curious to see how the boroughs of NYC compared against each other, here is the link of the condensed table.

Manhattan (at 19%) is the least physically inactive.  No surprises?  Manhattan is not as spacious and filled with mountains like Colorado.  Is it the tendency of the rich and well educated to be physically active?  Something to ponder.

On the other hand, all the other four boroughs perform abysmally.  Bronx and Brooklyn (Kings County) take the last 2 spots.  These counties are much more spacious than Manhattan (and hence less densely populated).  My theory is that geography probably has limited influence on the level of physical activity.  The level of physical activity of a region has more do with the level of education, income and culture of the group in that location.

I hope the insurance companies are tweaking their models (Is it legal?) using this data.  Now, I can use this as an argument to convince my friends not to move out of Manhattan as they might have to pay higher premiums.  Oh yeah, I forgot to mention that Westchester county on the other hand has almost similar numbers (at 19.8%) as Manhattan.  If you really want to move out of Manhattan, move to Westchester.

Thesis not wasted!

It's been almost 5 years since I graduated with a Masters degree.  Unlike others, it seems like my work didn't go waste.  According to this blog post by Google, this is a "world-class sentiment analysis system".  Attached is the paper for reference.  And I'm glad, those 2 years in grad school didn't go waste.
