       | Interestingly enough, the mean center of population for NY State
       | is only about 9 miles from the NJ border. Given NYC's location,
       | not suprising. I wonder if there are any states with centers of
       | population closer to the border than that. Given NY's geometry,
       | if NYC continues to grow relative to upstate, I could imagine the
       | center of population of the state actually being outside of NY
       | State boundaries.
       | 
       | It's also possible in the past the NJ's state center of
       | population might have been in NY - if Newark and Northern NJ were
       | more relatively populous, I think that the mean center of
       | population might be in Staten Island or the NY-NJ harbor.

         | After a brief search, Hawaii's is in the ocean between O'ahu
         | and Moloka'i. DC's might be the closest to the state border
         | (about 3.1 miles) but still just about directly in the center
         | of the DC polygon.

         | haha.

         | Do an animated video of a US map, where the mean center of

         | For Delaware, I eyeball the distance from the center of
         | population to the nearest border (again NJ) at maybe three
         | miles. But Delaware's so small that I feel like that doesn't
         | count; something like (distance to border)/(square root of
         | state area) might be worth looking at.

           | Google Map's measurement tool is giving me a hair under 5
           | miles which beats out Rhode Island.

           | Definitely-would want to normalize distance by total state
           | size, your formula works. I'm pretty sure NY would be the
           | winner here, although Alaska might also be close by this
           | metric.

         | Portland.

           | For oregon the population center is almost exactly Detroit.

             | Assuming this is true, and it makes sense that it would be;

       | for those interested: the mean center of population for the US is

       | It is interesting that two smallest shifts in mean center of
       | population are 2010-2020 and 1910-1920.
       | 
       | The largest shift appears to be 1850-1860 - perhaps due to the
       | California Gold Rush?
