32. t is possible to calculate standard errors for weighted estimates produced from the microdata This method is known as the 30 group Jack knife variance estimator For data items that are only applicable to the Labour Mobility Survey refer to About the Data Items List Under the Jackknife method of replicate weighting weights were derived as follows e 30 replicate groups were formed with each group formed to mirror the overall sample where units from a collection district all belong to the same replicate group and a unit can belong to only one replicate group e one replicate group was dropped from the file and then the remaining records were weighted in the same manner as for the full sample e records in that group that were dropped received a weight of zero This process was repeated for each replicate group i e a total of 30 times Ultimately each record had 30 replicate weights attached to it with one of these being the zero weight Replicate weights enable variances of estimates to be calculated relatively simply They also enable unit records analyses such as chi square and logistic regression to be conducted which take into account the sample design Replicate weights for any variable of interest can be calculated from the 30 replicate groups giving 30 replicate estimates The distribution of this set of replicate estimates in conjunction with the full sample estimate based on the general weight is then used to approximate the v
33. ts from a sample survey to infer results for the total population To do this a weight is allocated to each sample unit The weight is a value which indicates how many population units are represented by the sample unit The first step in calculating weights for each person is to assign an initial weight which is equal to the inverse of the probability of being selected in the survey For example if the probability of a person being selected in the survey was 1 in 300 then the person would have an initial weight of 300 that is they represent 300 people Separate weights were calculated for LFS and Labour Mobility Survey samples as some units were in scope for LFS but not for the Labour Mobility Survey The LFS weighting method ensures that LFS estimates conform to the benchmark distribution of the population by age sex and geographic area and also LFS region by sex two sets of benchmarks Weights are allocated to each sample respondent according to their state territory of selection state territory of usual residence part of state of usual residence age group and sex Back to top Benchmarking The weights were calibrated to align with independent estimates of the population referred to as benchmarks in designated categories of sex by age by area of usual residence Weights calibrated against population benchmarks ensure that the survey estimates conform to the independently estimated distribution of the population rather than to
