Random
We use rim weighting to make our sample representative of the demographic profile of the Greater Manchester region. In particular we weight our data to match ONS targets on the following variables: age, gender, borough, ethnicity, employment status
Because only a sample of the region was interviewed, all results are subject to margin of error, meaning that not all differences are statistically significant. For example, in a question where 50% (the worst case scenario as far as margin of error is concerned) gave a particular answer, with a sample of 1000 it is 95% certain that the ‘true’ value will fall within the range of 3.1% from the sample result. This is based on the current Census 2021 figures of approximately 2,867,769. Sub-samples from the cross-breaks will be subject to higher margin of error. Conclusions drawn from cross-breaks with very small sub-samples should be treated with caution.
