Additonal Data Sets Added

The statistics from the 1990 and 2000 censuses join the previously available data sets from the 2010 Census and the American Community Survey. In addition, 2011 American Community Survey estimates for the new districts formed for the 113th Congress are also now available.

2000 SF Census data

Hi,

 

Great job on the API!! It is very fast, and very easy to use. I am a developer, and know how hard it is to write programs that scale.. and you seem to have done a great job..

 

Just a quick question, I'm curious. I was wondering if you planned on releasing the 2000 SF Census data as well through the API? if so, do you have a target date for this?

 

Thanks

Problem with List of State Codes and Zip Code Search

I'm trying to retrieve the population for a certain zip code. What I found in your online documentation is that I should use the following URL string: http://api.census.gov/data/2010/sf1?key=(key)&get=P0010001&for=zip+code+tabulation+area:(zip)&in=state:(state) ...where (key) is my API key, (zip) is the zip code, and (state) is a two digit code that you use to identify states. The problem that I run into is that I ...more »

Zip/County/City Radius Tool

We are trying to create a tool where a user would:

1) Enter in their "home" zip code

2) Enter in a radius in miles

3) Hit an "Update" button.

 

Once the user hit the Update button, the screen would show all zip codes, all cities and all counties within the specified number of miles from the home zip code. Can these Census tools be used to create such a system?

Comparing ACS data from year to year

Now that 2007-2011 ACS 5 year data is available in the API, please see this guidance on comparing ACS data. http://www.census.gov/acs/www/guidance_for_data_users/comparing_data/ From the page: The Census Bureau recommends that you: DO compare estimates from non-overlapping periods, for example, compare a 2005-2007 ACS 3-year estimate to a 2008-2010 ACS 3-year estimate. DON'T compare overlapping periods, for example, ...more »

Trying to understand the Zip Code issue

Please bear with me, I'm new to this. I have been looking for a way to get Zip+4 demographics. The Census position is that they don't provide that but they point to the shapefiles. I have 2 questions: 1. Can someone simplify whether or not these shapefiles are useful or if the data I want is simply not available here? Example: what is the Male-Female ratio in 68198-9550? 2. What are other companies offering when ...more »

subject matter search

Census has added the very helpful restructured subject matter item lists (eg, http://api.census.gov/data/2000/sf3/variables.html). Thank you. I am seeking an easy way to search for two or more keywords (eg, Age, Hispanic) in a nonphrase structure that will highlight rows/items that meet that condition. ... by searching on the unmodified html. Any thoughts on this? Thank you.

Commercial/External APIs already interfacing with this data?

Hi, Are there any commercial/free APIs that are available for developers to use that are ALREADY sourcing from the Census.gov datasets? Factual's Geopulse Context was doing so as recently as 2013 but they've deprecated their API. It generated easy to access and useful demographic data from a lat/long and made importing into chart libraries super easy. Anyone know of anything similar? Happy to pay $ for a service that's ...more »

zip code level data from 2000 survey

HI:

 

I am trying to download zip level data for 2010, 2000 and 1990 census demographic data. I have no problem for 2010 data by using the url:

http://api.census.gov/data/2010/sf1?key=*&get=P001001&for=zip+code+tabulation+area:*&in=state:48

Is there anything similar for 2000 and 1990 data?

 

Thank you

Obtaining census tract numbers

Can I use this API to create an easy way for users on my website to get their census tract number without using a map? I simply want the users to input their residential address into text fields. Hopefully this API will spit out their 10 digit census tract number after input. I would prefer NOT to redirect applicants to a 3rd party site. I ultimately want to use the census tract number from the API to reconcile it with ...more »
