Lifetime and 12 Month Prevalence Estimates of Violence
Lifetime prevalence refers to the proportion of people in a given
population who have ever experienced a particular form of violence.
Lifetime prevalence estimates are important because they provide
information about the burden of violence within a population.
12 month prevalence provides information about the proportion of
people in a given population who have experienced a particular form of
violence in the 12 months prior to taking the survey. Twelve-month
prevalence estimates provide a snapshot of the recent burden of
violence in a population. When collected over multiple years, 12 month
estimates can be used to assess trends in the burden of violence over
time (suggesting whether violence may be increasing or decreasing).
I suspect the figures which you quote are as reported.
The "weighting" is to try to account for people who don't answer the survey -- page 13 says,
Statistical inference for prevalence
and population estimates
were made based on weighted
analyses, where complex sample
design features such as stratified
sampling, weighting for unequal
sample selection probabilities, and
non-response adjustments were
taken into account. The estimates
presented in this report are based
on complete interviews.
So given that the sets of numbers don't match, I assert that the reason for those numbers is (as for all their numbers) that they're simply reporting what they were told by the people being surveyed.
FWIW my hypotheses for the discrepancy are that it could be either:
Misreporting by the people being surveyed (the men's looks less likely to me than the women's, with the men reporting a lifetime rate of only 4 times higher than the yearly rate)
A recent significant increase in the rate of violence against men (reflected in the recent 12 month figures but not evident yet in the lifetime figures), which is the kind of phenomenon which the "12 month prevalence" questions were intended to assess (as stated at the end of the second paragraph of the "Lifetime and 12 Month Prevalence Estimates of Violence" quote above).
