I’m using ACS data (along with admin data) to generate a Supplemental Poverty Measure for Oregon. I have created new SPM resource units, which are defined somewhat differently from the ACS household/family, and I need to generate new household weights to go along. Two questions:
- Is it reasonable to assign a new HHWT number based on my new resource unit definition?
- Can I just use the same basic formula for assigning HHWT to a new household weight? Based on a glance at ACS data, it looks like each member of the household just gets assigned a household weight (HHWT) based on the household head’s person weight (PERWT).
- One odd thing – the formula above does not always work in a precise way – in some 1-person households, their HHWT is one point higher than their own PERWT (e.g., 276 vs 275; 33 vs 32) – why is this – a rounding issue? – and do I need to worry about it?
