RE: National vs Metro Area Variables

We are all saying the same thing as for sources of information. It all depends on what the information if being used for. HUD Data Sets combined with local data has made my job much easier and I use all these sites to customize my reports to determine the need for affordable housing developments in DDA's and market rates. Thanks for all your hard work in each department.

HUD and the Census Bureau work together on the CHAS data, a custom tabulation of the ACS. The primary purpose of the CHAS is to incorporate HUD income limits into the ACS and cross-tabulate that information with other household characteristics. Of course it is much less detailed than the AHS (especially on characteristics of the housing unit) but it provides a wealth of information about households in different AMI categories. The CHAS data are also available at smaller levels of geographies, like cities and census tracts.

The CHAS data and more information are available at: 2008-2012 CHAS will be posted within the next week or two. If anyone has questions, feel free to contact me.

If you want to further analyze households that fall into a particular tier relative to AMI, or the homes they live in, you pretty much have to use the AHS.

P.S. HUD sponsors or co-sponsors a number of very useful housing surveys, but I don't think it's directly involved in the ACS.

I suppose it depends on the nature of the analysis, but if a person simply wants to analyze household incomes at various AMI levels, wouldn't the Census Bureau/HUD American Community Survey provide metro area estimates that would be more current than the AHS? Just wondering...

Hey Doug,

We have that data available but it appears we have not posted it yet. If you need 2013, send me an email at If you are looking for 2011 or before, they are at:

For everyone else,

We'll get the 2013 HADS files posted on the above website by end of this week.

Can anyone explain why variables that seem to be based on the metro area level are only available in the national file? For example, L30, L50, L80, etc. It seems that to calculate whether a household is at 30% AMI is dependent on what metro area they are in, but this is not included in the metro AHS data file.

We are interested in comparing low and medium income families at the metro area in Florida. It seems that it would be possible to roughly calculate these L30, L50, & L80 variables, but the fact that they are not released on the metro area has me concerned that this implies that calculating them might have the wrong weights when using WGTMETRO.

Should I be concerned with this weight issue, or can you merge national variables with metro variable via the CONTROL variable?

Any help is appreciated,

Douglas White
