Graphical summary

Commentary

Overview

Other chapters in this report have each considered a single topic. This chapter draws together data for multiple topics in a single graphic. The graphic compares the seven territorial authorities making up the Auckland region, using 15 demographic, social, and economic indicators.

Interpreting dot plots

The data are presented below using dot plots (Cleveland, 1994). Dot plots convey the same information as bar charts, but more efficiently. Figure 15.1 shows a dot plot and the bar chart equivalent.

Graphical comparison of Auckland's territorial authorities

The Auckland Regional Council area contains seven territorial authorities. The Interpreting the maps chapter has a map of the territorial authority boundaries. Franklin district falls partly within the area of the Waikato Regional Council, and partly within the area of the Auckland Regional Council. This chapter, like the rest of the report, only shows data for the parts of Franklin district that fall within the Auckland Regional Council area.

Figure 15.2 brings together 15 demographic, social, and economic indicators. The hollow dots show data from the 1996 Census and the solid dots show data from the 2006 Census. Definitions for the indicators are in table 15.1.

Highlights

  • Auckland city and North Shore city have experienced declines in the percentage of the population aged 0–14 years and the percentage aged 65 and over.
  • All territorial authority areas have seen falls in the percentage of people who were at the same address as five years earlier, and rises in the percent who were overseas five years earlier.
  • Manukau city has the smallest proportion of people with a European ethnicity, but does not have the biggest concentration of recent migrants. The biggest concentrations are in Auckland city and North Shore city, both of which have proportionally more people who were overseas five years ago than Manukau city does.
  • Median incomes increased for all territorial authority areas between 1996 and 2006, but so did median rents.
  • Residents of Auckland city are more likely to have a university degree than residents of North Shore city, but median incomes are higher among North Shore city residents.
