The census tells us about a vast range of things – such as migration, travel to work, housing stock and car ownership, family structures and household relationships – but it is absolutely critical to our iran rcs data understanding of the basic counts, without which prevalence rates cannot be meaningfully calculated.
Turning to the geographical areas, the MSOAs are built up from two layers of smaller geographical areas – census Output Areas and Lower Layer Super Output Areas (LSOAs). for the 2001 Census and represented a major break from previous practice.
Rather than designing areas by hand in advance of the census, the Output Areas were computer-generated using an automated zone design process once the data had been collected, ensuring that every area contained a broadly similar population count and meeting a host of other design requirements, most importantly that no population is too small to protect the confidentiality of the people that live and work there.
