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.

COUNTY lookup by valid street address

I am looking for a solid WebService API method that will allow me to submit an http request with a pre-validated US Street/City/State/Zip address and return COUNTY in xml or json about 200 times per work day.It looks like the US Census API may do it? Is the data current enough? What might a request look like? Many thanks in advance.

Access Micro-data for Blocks

I'm working on a school project with 2010 Census data. Currently, we are getting tract-level data using codes from http://api.census.gov/data/2010/sf1/variables.json to get data. For example, to find the white 65-year old males in a county's tracts, we make the API call: http://api.census.gov/data/2010/sf1?key=[key]&get=PCT012I068,NAME&for=tract:*&in=state:08+county:059 However, when making the same call at a block ...more »

API extension for query across hierarchy

Hi All, The API has incredible functionality for query/results within the nested US Census Bureau Geography (e.g. getting data for all the tracts in a county or all the block groups within a track). However, it does not appear to support queries that run across the same geography very well. For instance It does not appear to allow me to query the same parameter (e.g. race) in Tract A within County B and Tract C ...more »

ZCTA in ACS 2012

Hi,

API supporting multiple geography query

Hi All,

I have been working on my application and one of the things I would like to do is query the same variable on multiple geographies. For instance, get the total population at the Block Group, Tract, County, State, and Nation.

 

Right now, it is my understanding that this would represent five different calls to the API.

 

Can this be done in one call to the API ?

2012 data profiles and jam values

Please note that the 2012 data profiles may return the following in place of data. We will update the documentation on the website. An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate. An '-' entry in the estimate column indicates that either ...more »
