National Insurance number
The National Insurance number is used as a reference number in the Pay As You Earn system, and also by the self-employed. It is also used in applications for Individual Savings Accounts (ISAs), to check that an individual has opened only one ISA in a tax year.
Social care in England
In England, the social care workforce comprises over one and half million people. An estimated two thirds of the workforce work for some 25,000 employers in the private and voluntary sectors. The remaining third work in the statutory sector, largely for 150 local councils with personal social services responsibilities. Data on the social care workforce is collected and analysed by Skills for Care, the national workforce organization for adult social care in England. Data is collected on the social care workforce through Skills for Care's National Minimum Data Set (NMDS-SC).
