Economic » Prosperous Community

All members of our community prosper from a strong and growing economy. A thriving business sector attracts and retains a skilled and productive workforce.

What is Prosperous Community?

A prosperous community is one in which there is a job market in which employment is growing, unemployment is low, incomes are relatively high and evenly distributed and people are well-educated. Having a decent income is a crucial element contributing to quality of life because most basic needs such as food, water, shelter, health care and many forms of recreation have to be purchased. The valuable services resulting from unpaid household and community work also contribute directly to our well-being and prosperity.

The prosperous community outcome is made up of eight indicators that were selected to measure progress towards the outcome definition (shown above). Please see below for the data relating to each of the prosperous community indicators.

Prosperous community GPI, 2001-2018

What this means

The prosperous community index of the WR-GPI rose steadily between 2003 and 2008. However, the economic impacts associated with the fall-out from the global financial crisis (GFC) created a sharp reversal of the positive trend at 2008, and the index was negatively affected for the following four years with signs of recovery evident in 2013. A net change for this index between 2001 and 2017 of 13%. 

Did you know?

A GPI is an attempt to measure whether a nation’s or a region's growth, increased production of goods, and expanding services have actually resulted in the improvement of the well-being of the people in the region.

Income inequality

Why is this indicator important?

Income equality is often regarded as a measure of the fairness of the society in which we live. A high level of income inequality may be detrimental to the level of social connectedness across society and research has suggested a negative relationship between income inequality and other factors with an influence on well-being such as trust, social mobility, health outcomes, and the rate of imprisonment.

The P80/P20 ratio is calculated as the ratio of the household income at the 80th percentile (i.e. 20% below the wealthiest household) to the household income at the 20th percentile (i.e. 20% above the lowest income household) (Perry, 2005). Overall, as household income inequality increases, the P80/P20 ratio also increases, and therefore the more unequal society is.

P80/P20 ratio of equivalised gross weekly household income, 2007-2017


  • In the year ending June 2017, the P80/P20 ratio of equivalised gross weekly household income in the Wellington region is just below 3.9, up from 3.7 in the previous year 2016.
  • Between 2009 and 2017 the ratio continues to fluctuate for the Wellington region. 
  • The ratio has been consistently higher in the Wellington region than for New Zealand overall. The ratio for New Zealand at 2017 was 3.4. The national ratio has also fluctuated across the period 2010-2017.
