n. — Administration, often in compounds, e.g. National Child Benefit Supplement
between 1991 and 2016, a joint federal, provincial and territorial government program aimed at decreasing child poverty by providing financial support to low-income families.
Type: 1. Origin — In 1998, the federal government enhanced the existing Canadian Child Tax Benefit by introducing the National Child Benefit, which provided monthly payments to low-income families with children. The NCB also offered other benefits and services to these families (see National Child Benefit reference). In 2016 (see quotation of that year), the NCB was combined with other benefits into a Canada Child Benefit.
The term is almost exclusive to Canada (see, e.g. Chart 1). It was first used in the early 1990s when the legislation for the program was proposed.
See also COD-2, s.v. "National Child Benefit", which is marked "Cdn".
