It might have something to do with the census, since the last time it was carried out was in 2000. Maybe it refers to the maximum population increase in a region ?

It's the centroid of the population distribution in the US along the years.

DE(first state), east coast, where the initial US settlements were.

The purple triangles indicated the trend of increasing western (mid-western) settlements ever since.

In what sequence (years) the British made settlements in the US?

Sailesh Ganesh said...

The geographical center of US population at the end of each decade?

Congrats to Nikhil and Sailesh for nailing it and Ishani and Ankur for getting the drift! Thanks Misfit for playing.

It is indeed the geographical center of US population showing the westward expansion under "Manifest Destiny" and the recent southward dip with immigration across the southern border.
