Census Geography

Determine street address from different geo coordinates

Is there a proven formula to match up slightly different lat/lng values to a street address without submitting both of them to a Geocoding service (since we've already done so and don't want to make a second api call). eg. The following coordinates are for the same street address (55 Church Street zip code 07505), but one set points to the building and the other to the street. lat : 40.9170109 long: -74.1702248 lat: ...more »

Inconsistent Output in Geocoding Services API?

Hi Everyone, First off, I want to congratulate you on putting together such a comprehensive and straightforward set of APIs. This is really excellent work, and it's a great way of making Census Bureau data more accessible. However, in integrating with the Geocoding Services API, I seem to have noticed a bit of an issue: when looking up Geographies, the results are inconsistent. In particular, if I execute an identical ...more »

How to get api to do geocoding?

I have used Tele-Atlas/TomTom geocoding service which is now been discontinued. I'm trying to find an alternative that would return most or all of the same variables.

1. How do I get access to the API?

2. How is the security? My data is highly sensitive and I have to be 100% there will be no way the data can be viewed or saved.

3. I have to geocoding around 100,000 addresses. Will this be an issue?

Thank you

IN Clause for Census Tracts within New York City

I want to retrieve tract level data for all of New York City. I know I can do this using five different calls, one for each of the five counties. I would like to do this with a single call. I have read that the IN clause does not support this (&in=state:36+county:005,061,047,081,085 only returns records for 005). Perhaps this could be done using a place but this is currently not a supported geographic hierarchy.

Invalid API Key Message

Hello, I recently obtained and validated my API key. However, when I attempt to enter a test URL in my browser window with my api key I receive a message stating "A valid key must be included with each data API request. You included a key with this request, however, it is not valid. Please check your key and try again."

API - Pass a point to server return data

Newbie question. What I want to do is given an x, y coordinate, I want to pass it to a Census server and have it return data for the block group it intersects.

Very Slow Response Times

Since about mid day yesterday I started to see very slow response times. Even selecting one variable is taking approximately 10 seconds. Requesting 50 is take minutes and sometime the server returns an an error: There was an error while running your query. We've logged the error and we'll correct it ASAP. Sorry for the inconvenience. This is a bit hard to test as there appears to be server side caching so if you ...more »

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.

Trouble getting daytime population

Hi everyone, I'm trying to calculate the daytime population at the block level and/or the block group level. It's noted here (https://www.census.gov/hhes/commuting/data/calculations.html) that we can query the API and get the code "B08604 Total Workers for Workplace Geography." However, this code returns the "null" value in various data sets (including ACS 5-year) at the block-group and block level. It seems like ...more »

Merging Table Lookup and Shell Files

In order to get the proper titles for variables/cells in the data I needed to write a program to merge two Excel files. The two files are Sequence_Number_and_Table_Number_Lookup.xls and ACS2012_5-Year_TableShells.xls. The first one contains the sequence and line numbers so that I can get the values from the data-tables. The second one has indents in the cell titles so I know how to combine them to create a proper cell ...more »

Add GET parameter for tables

There is a limit of 50 variables in a GET. So, I can understand, sort of, the need to limit, but many of your tables have more than 50 cells. For example: [ACSSF, B04001, 0006, , 7, 109 CELLS, , FIRST ANCESTRY REPORTED, Ancestry], has 109 cells, and if I want to get Estimates plus Margin of Errors I need to get 218 variables. So, why not accept a table number parameter instead? It would make the calls much easier and ...more »

Can't get an API Key

Hi,

I've tried for several days to request an API key from the census developers site with no success. I have filled out the form trying a couple different email addresses and have not received any additional information. I've checked my spam folder in each of the email accounts and no results there either. What is my next step to get an api key?
