4/27 - Sample numbers

Before the analysis begins, we must consider whether our dataset is large enough to analyse, and whether there are sufficient numbers of people who have moved to a communal establishment by 2001 to allow further sub-classification by type of household and other characteristics. The answer to the first question is that the dataset contains 35,097 people which is more than adequate for any type of analysis! And among them are 2,745 who moved to a communal establishment, a small proportion (8%) but sufficient in number. If numbers were sparse, disclosure problems might well arise with the study; these are dealt with in the Outputs training module.
