No 'Access-Control-Allow-Origin' header is present on the reques

Hi, I had a little app working until just two days ago, when I started receiving a CORS error: "No 'Access-Control-Allow-Origin' header is present on the requested resource". I tried adding the jsonp callback to no avail. I am able to access the generated url via the browser. What I am doing is generating state options for a select list. The offending function, getStateList(), can be seen at: https://github.com/Code-for-Miami/iam1of.us/blob/master/js/script.js#L97 ...more »

Census Data Acquisition from Boundary Files

On this site: https://sites.google.com/site/stephaniesmullen/google-map-examples/census-data-acquisition the author uses census boundary files to get coordinates of points that make up the boundary of a polygon. When I tried to do the same thing with boundary files of block groups from the 2010 census for California. One of the files contents was in hex format and the block groups arrangement of polygon data ...more »

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 »

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 »

Improving API documentation

Example of easier to follow API documentation: http://developer.usatoday.com/docs/read/Census Versus no coded variable definitions on the page: https://www.census.gov/developers/data/ All the needed content is in this presentation, but it was not intuitive to click on it since it refers to a specific event: https://www.census.gov/developers/NDoCH_Support_Slides.pdf Maybe rename it "ACS API Handbook"?

Census Data for Federal Grants

Many federal grants require applicants to supply Census data when responding to RFPs. Allow agencies to create a report template in AFF for applicants. This would allow for applicants to enter an address and get centroid data that was predefined by the agency. Applicants could downloaded the table in PDF form efficiently with all the available data the federal agency requires.

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

Difference between Data Profile and Summary File API?

What is the difference between the Data Profile data and the Summary file data. It seems very similar, with some overlap, but also slightly different, and I don't understand the relationship between the two. Is the Summary File information used to create the Data Profiles? Are these two totally different surveys with different metrics? It's not clear to me when I should use the Summary File vs Data Profile. I've leaned ...more »

ACS 2011 1 Year

Is there a specific reason that 2011 1 year data is only available by Congressional District? I've been asked by one of our business analysts, and wanted to provide an accurate answer.

 

Thanks in advance for any insight!
