type | the data type (text, number, boolean)
#### Example
Add a Measure to an empty column based on point locations in your table
```SQL
UPDATE tablename SET local_male_population = OBS_GetUSCensusMeasure(the_geom, 'Male Population') -> 'value'
UPDATE tablename SET local_male_population = OBS_GetUSCensusMeasure(the_geom, 'Male Population')

Get a measure at a single point location

SELECT * FROM json_each(OBS_GetUSCensusMeasure(CDB_LatLng(40.7, -73.9), 'Male Population'))
SELECT OBS_GetUSCensusMeasure(CDB_LatLng(40.7, -73.9), 'Male Population')
