Using Data

List of all Legislature District "names"

I need a list of all the states' legislature's district names. I will use this list as the definitive list of district names that data is mapped to. I tried to use the " Census Name Lookup Tables" found here:
https://www.census.gov/geo/maps-data/data/nlt.html
but there are many district names that don't map properly to the district names returned by the 2012-5yr-ACS API. So, for example, if I submit the query:
http://api.census.gov/data/2012/acs5?get=B19301_001E&for=state+legislative+district+(lower+chamber):*&in=state:50... more »

Using Data

Getting null from ACS block-group query

For ACS data - is there a way to tell which codes are valid for tracts vs block group?

Some codes work for both, some return "null" when the block-group level is queried.

For example, the following url works for the tract level:
http://api.census.gov/data/2010/acs5?key=4be82289939444f20513cd7c3c3eafb42e0d9ccf&get=B06007_003E,NAME&for=tract:*&in=state:08+county:059

But using the same code, it returns null for the... more »

Using Data

Block Data from ACS

In looking at the geography levels supported by 2012 ACS, I don't see block-level data.

See:
http://api.census.gov/data/2012/acs5/profile/geography.json

I am looking for block data support like this (that I'm using from 2010 decennial survey):
{
"name": "block",
"requires": [
"state",
"county",
"tract"
]
}

(http://api.census.gov/data/2010/sf1/geography.json)

Is there another/better... more »

API Variable Question for ACS2011 5 Year

Preface: New to API Calls & Census Data (not sure the proper Campaign to post on)

Curious, how can I more efficiently pull data through the API without having to specify each individual Unique ID (found in the ACS2011_5-Year_TableShells.xls file)?


If I wanted to pull all data for Table ID: B01001 what would my {&get=} be?

Currently, I am using each individual Unique ID as so:
http://api.census.gov/data/2011/acs5?{key}&get=B01001_001E,B01001_002E,B01001_003E,B01001_004E,B01001_005E,B01001_006E,B01001_007E,B01001_008E,B01001_009E,B01001_010E,NAME&for=state:06... more »

Using Data

Combining ACS Data with Crime Data

In order to understand how crime or criminal elements are embedded within different communities, it may be useful to combine neighborhood crime data with ACS demographic and housing data. There are hotspots in most cities that could be objectively analyzed to reveal patterns which may be disrupted by governmental policy. That is, if the data clearly points to consistent reliable trends.

High Risk/Vulnerable Individuals

To help local governments better plan for disaster recovery for their residents, it would helpful to know which areas contained high risk/vulnerable individuals. These individuals might include the elderly, small children, disabled individuals, those who are language isolated, and those who do not have access to a vehicle. Creation of heat maps, or other visualizations of these populations can help emergency management... more »

By mashing these two APIs (http://www.meetup.com/meetup_api/, http://www.census.gov/developers/data/) together, community builders can identify groups and leadership/influencers that exist within areas of interest. Hopefully enabling a sort of distributed knowledge management system.... more »

ACS data for zip code tabulation area

Hi all,

I am trying to use the api to collect information for zip code tabulation areas from the ACS 2011 survey.

I have tried several variations of the following url, but get an unsupported/unknown geography error:

ACS2010 sf1 table mapping

I am trying to make sense of the table name convention for the ACS data.

Unlike the 2010 Census SF1 document (http://www.census.gov/prod/cen2010/doc/sf1.pdf), the tables listed in the 2010 ACS SF1 document (http://www2.census.gov/acs2010_5yr/summaryfile/ACS_2006-2010_SF_Tech_Doc.pdf) don't seem to correlate to the api.

For example, an attempt to query:
