Equity is essentially about fairness, and implies that the most vulnerable and needy groups within a society require access to greater resources than those communities that are more robust. This equity is different to equal shares or equal opportunities. For example, equal shares would mean every district having the same amount of money to spend on each person.
Equity is a measure that compares one group with another.
For example rich with poor, black with white, rural with urban and women with men. The long term goal of promoting equity is to improve the health of the most vulnerable groups. Equity in the Late 1900's Around the world issues of equity are becoming of ever greater concern. The income gap between the fifth of the world living in the world's richest countries and the fifth in the poorest was 74 to 1 in 1997, up from 60 to 1 in 1990 and 30 to 1 in 1960. An equity gauge is above all a means of tracking gaps in health status at national or sub-nation level.
