How should I do in order to replicate the number of households by using IPUMS-CPS?

CPS

I have been trying to replicate by using IPUMS-CPS. However, the number I calcurated by using HWTSUPP weight is not equal to the official number. Specifically, I simply summed up HWTSUPP weight of each hosehold, but the total number (123,053 thus. units) is a little different from the official number (123,229 thus. units).

How should I do in order to replicate the number of households by using IPUMS-CPS?

Thanks.

I forget attaching the source of the official number: http://www.census.gov/hhes/families/d…

Unfortunately, I am also unable to replicate the official household counts in the Census Bureau tables. Official estimates can sometimes differ from the publicly-available microdata, but the cause is not always clear. While the difference could be caused by population revisions or confidential changes to the data, the documentation included with the Census tables does not suggest a reason for this discrepancy.

Sorry that I could not deliver better news.
