Query all sublayers

Hi All,

I am curious to know if there is an efficient method to query all the sublayers of a map.

For instance the USA Population Density (http://server.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Population_Density/MapServer) has data in sublayers at the State, County, Tract and Block Group levels. 

If I had the Block Group level displayed, what would be an efficient method to query the same data (population density) at the Tract, County, and State levels ?  I am guessing that I actually need to query via the sublayer number (e.g. Block Groups (1), Tracts (2), Counties (3), and States (4))

Thanks in advance !
