The folks at the Inquirer saved me a heck of a lot of work. I was about ready to start extracting the Frankford data from the census and now I find that they have done it for me and far better than I could. So you can see their work here.
The bottom line is that Frankford saw an increase of 3.7% (total in 2010 38,459) since the year 2000. The area of Frankford includes Northwood, East Frankford and much of the area as far as Aramingo Avenue I believe. Significant decrease in the number of white folks was offset by increases in the numbers of Black and Latino. Even the Asian population went up by 0.9%.
See the chart below from the Inquirer for the specifics:
