We show here how you can access measures through the CartoDB Editor. The same methods will work if you are using the CartoDB Platform to develop your application. We encourage you to use table modifying methods (UPDATE and INSERT) over dynamic methods (SELECT).
## OBS_GetUSCensusMeasure(point geometry, measure_name text);
## OBS_GetUSCensusMeasure(point geometry, measure_name text)
The ```OBS_GetUSCensusMeasure(point, measure_name)``` function returns a measure based on a subset of the US Census variables at a point location. The ```OBS_GetUSCensusMeasure``` function is limited to only a subset of all measures that are available in the Data Observatory, to access the full list, use measure IDs with the ```OBS_GetMeasure``` function below.
