**Sampling Weights**

Our objective is to describe living conditions based on a representative
sample of individuals and households. By "representative", we mean
that we have applied probability sampling procedures such that each individual
and household in the population has a known chance of being selected.

In order to make comparisons of sub-populations like regional center
residents and village residents, we grouped the population (stratified it) and
sampled from each group. The probability of selection could differ between
groups, but not within groups. For example, the probability of selection could
differ between households in regional centers and villages, but not within a
regional center or within a sampled village.

Sampling weights take into account known differences in the probabilities of
selection between groups to yield a representative sample. There are four
sampling weights for the Alaska dataset:

VILINDWT

VILHHWT

REGINDWT

REGHHWT

The two weights beginning with "REG" yield estimates for the three
regions (N. Slope, Bering Straits, Northwest Arctic) as a whole. The weight
including "HH" yields estimates for households. The weight including
"IND" yields estimates for Inupiat adults, aged 16 and over.

Similarly, the two weights beginning with "VIL" yield estimates for
households ("HH") and adults ("IND"). These weights should
be used when comparing results for just the sampled communities.
