Changes in Lorton, VA

I compared two separate census tracts on the map who are adjoining one another.  I wanted to see what caused such a change in the percentages of race between these two geographical areas as they are only divided by a road.

Using the Census tract 4222 and 4221 from the Census tracts of 2000, there is clearly a vast difference between 4222 and 4221.  In Census tract 4222 there is an overwhelming percentages of blacks in this area alone, 93% compared to 2.8% for whites.  But just down the road 2 miles, during the same time frame, blacks and whites percentages where more even, 32% and 48% respectively.

Since there are no Census tracts for 4222 and 4221, I had to use the closes Census available which was in 1970.  Census Tracts were different numbers so 4221 today is Census Tract 4028 in 1970 and Census tract 4222 is Census tract 4029 in 1970.  The black population in Census Tract 4028 was at a very high rate compared to Census tract 4029 just on the other side of the road.  From 1970 to 2000 the percentages of blacks to whites didn't change much but you can definitely see the increase in other races coming into the area.  As seen below.

And finally with the ACS of 2006 - 2010 the numbers dropped off dramatically in Census Track 4221 with the numbers of blacks decreasing along with the population.  Census Track 4222 increased in population and in the dynamic of many different races moving to this particular area as you see below.
