National Insurance number
The National Insurance number is a number used in the United Kingdom in the administration of the National Insurance or social security system. It is also used for some purposes in the UK tax system. The number is described by the United Kingdom government as a "personal account number".
Guaranteed minimum income
The United States has multiple social programs that provide guaranteed minimum incomes for individuals meeting certain criteria such as assets or disability. For instance, Supplemental Security Income (SSI) is a United States government program that provides stipends to low-income people who are either aged (65 or older), blind, or disabled. SSI was created in 1974 to replace federal-state adult assistance programs that served the same purpose. Today the program provides benefits to approximately eight million Americans. Another such program is Social Security Disability Insurance (SSD or SSDI), a payroll tax-funded, federal insurance program. It is managed by the Social Security Administration and is designed to provide income supplements to people who are physically restricted in their ability to be employed because of a notable disability, usually a physical disability. SSD can be supplied on either a temporary or permanent basis, usually directly correlated to whether the person's disability is temporary or permanent.
