getting census data given an address

Question

After using locator, what do I need to do to get the census data (block and tract in particular) for the particular address? The info in available by creating a querytask to this url http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/0

I don't have any idea what information from the locator function I'm supposed to pass to get the info I need.

Thanks,

This is something I am looking at as well but am having problems... The idea is that the user enters an address, resulting candidate addresses are populated in a dojox data grid, the user then clicks on an address which then returns whether that address is within the query layer I have specified. My code is below - I have tried to include setting the query geometry inside the row click handler function using the candidate.location details but it seems to throw an issue about the wkid spatial reference being undefined - is there anything glaringly wrong with this? I am trying to populate a div if the map point is within the query layer. //CODE RIMS Find

Match

Address

see the sample at http://help.arcgis.com/en/webapi/javascript/arcgis/help/jssamples/query_nomap.html which shows how to query a dataset to return the values.

In this sample, they use query.text = stateName;

In your case, you would usequery.geometry = pt

where pt is the point result of your address query. See the Query help file more more info.
