Query help

Hi,

I've been working with the following query:

http://api.census.gov/data/2012/popproj/pop?get=TOTAL_POP,POP_4,POP_3,POP_2,POP_1,POP_0&ORIGIN=0&RACE=0&SEX=0&YEAR=2012&key=

I think it is returning total usa population of age 5 and under for the year 2012. Is there a way to get the same information for each state?

In other words is per state information available from popproj/pop? Or do I need to query another data set?

Thanks.
