Economic Standard of Living
New Zealand is a prosperous society, reflecting the value of both paid and unpaid work. Everybody has access to an adequate income and decent, affordable housing that meets their needs. With an adequate standard of living, people are well-placed to participate fully in society and to exercise choice about how to live their lives.
Economic standard of living concerns the physical circumstances in which people live, the goods and services they are able to consume and the economic resources they have access to. It is concerned with the average level of resources in New Zealand as well as the distribution of those resources across New Zealand society.
Basic necessities such as adequate food, clothing and housing are fundamental to wellbeing. The 1972 Royal Commission on Social Security agreed that a useful standard for adequacy was a level of resources that allowed individuals not just to survive but also to participate. They defined participation as meaning "no-one is ... so poor that they cannot eat the sort of food that New Zealanders usually eat, wear the same sort of clothes, [and] take a moderate part in those activities which the ordinary New Zealander takes part in as a matter of course".52
The desired outcomes statement points to the importance of not only everyone enjoying a decent standard of living, but also of our society being as prosperous as possible. Such prosperity gives people choice over how to live their lives.
Five indicators are used in this chapter to provide information on different aspects of economic standards of living. They are: market income per person, income inequality, the population with low incomes, housing affordability and household crowding.
The focus is largely on objective measures of economic living standards. Together, the indicators provide information about overall trends in living standards, levels of hardship and how equitably resources are distributed. All are relevant to the adequacy of people’s incomes and their ability to participate in society and make choices about their lives.
Market income per person gives an indication of the average level of income and therefore the overall material quality of life available to New Zealanders. This is an internationally-recognised measure, allowing comparisons between New Zealand and other countries. We also provide an estimate of the economic value of unpaid work.
Income inequality is measured by comparing the incomes of the top 20 percent of households with the incomes of the bottom 20 percent. High levels of inequality are associated with lower levels of social cohesion and personal wellbeing, even when less well-off people have adequate incomes to meet their basic needs.
The proportion of the population with low incomes also provides information about how equitably resources are distributed and how many people are likely to be on incomes that do not allow them to participate fully in society.
Housing affordability measures the proportion of the population spending more than 30 percent of their income on housing. Housing costs have a major impact on overall material living standards.
The final indicator measures the number of people living in overcrowded houses. Housing is a basic need, and this indicator provides a direct measure of the adequacy of housing people can afford.
