Hamilton where different age groups live

The 2018 census data on age is separated into four age groups. In Hamilton, 21% of people are under the age of 15 years  25% are between 15 and 30 years old, 42% are aged between 30 and 65 years, and 12% are older than 65 years (density 1,450 people per km2 (ppkm2)). At the small town level (census ‘Statistical Area’ (SA2)), Hamilton East is similar: 21% of people are under the age of 15 years, 24% are between 15 and 30 years, 44% are aged between 30 and 65 years, and 12% are older than 65 years (density 1,779 ppkm2). This is followed by Maeroa, with 21% of people under the age of 15 years, 26% between 15 and 30 years old, 43% aged between 30 and 65 years, and 10% older than 65 years (density 2,911 ppkm2).

The census has produced a good interactive map, which shows where different age groups are increasing or decreasing. The maps in this post loosely divide the population into three age groups, to identify concentrations in various areas. The maps above show that Temple View (271 ppkm2), Chartwell (2,790 ppkm2) and Porrit (2,135 ppkm2) have both a healthy number of children and older people. Crawshaw (3,766 ppkm2) and Rototuna North (912 ppkm2) both have high proportions in the under 15 year age group (29% of the population).  Older people are more concentrated in Flagstaff East (1,955 ppkm2), with 23% older than 65 years, 42% aged between 30 and 65 years, 15% between 15 and 30 years old, and 20% of the population under the age of 15 years. The most extreme separation of young and old can be seen in Crawshaw and North Rototuna; both these areas have a low number (6% and 7% respectively) of over-65-year-olds, which is the opposite to St Andrews (1,556 ppkm2), with its high percentage of over-65-year-olds (33%) and low number of under-15-year-olds (17%).

This next maps shows the distribution of future leaders (15 to 30-year-olds) and existing leaders (30 to 65-year-olds). As one would expect, Greensboro (8,138 ppkm2), near the university, has 62% of its population aged between 15 and 30 years. For the dominant age group (30 to 65 years) Kirikiriroa (524 ppkm2), Flagstaff South (1,726 ppkm2), Frankton Junction (191 ppkm2) and Western Heights (2,719 ppkm2) all have 49% of their population in this age group. Te Rapa south (29 ppkm2) has 53% percent of its 114 residents in the 30 to 65 year age group. One of the outcomes I like on these maps is how these two age groups are both attracted to areas across the city, ranging from Frankton Junction (191 ppkm2), through Kirikiriroa (524 ppkm2) and Whitiora (2,803 ppkm2) to Claudelands (2,209 ppkm2).

Population density in Hamilton 2018 Census

Posted on by 0 comment

Hamilton’s 1956 population density was 1,346 people per km2 (35,941 people, in an area of 26.7 km2 or 6,618 acres*). Today, the 2018 census puts Hamilton at 1,450 people per km2 (160,911 people, in an area of 111 km2). In the past (Hamilton city centre Louis Wirth measure), I was basing my estimates of density on Hamilton having an area of 98km2 and a population of 150,200, giving a population density of 1,532 people per km2 (ppkm2). *Hamilton District Scheme 1963 page 2

Greensboro, near Waikato University, is the stand-out ‘Statistical Area’ (SA2) at 8,138 people per km2 (3,795 people, in an area of 0.47 km2). This is followed by Swarbrick at 4,746 ppkm2 (2,400 people, in an area of 0.5 km2) and Melville North at 4,027 ppkm2 (2,772 people, in an area of 0.69 km2). In all these neighbourhoods, everyone lives within walking distance of local dairies and great open spaces. Note: Census 2018 uses ‘Statistical Area 2’ which is smaller than the 2013 census ‘unit areas’; as an example the Swarbrick unit area was previously 1.5km2.

Looking for ‘towns’ within Hamilton, the Nawton / Crawshaw area supports a population of 11,124 residents (with an area of 3.27 km2 this equates to 3,402 ppkm2). Everyone living in this area is reasonably near to retail, schools and employment.  The next largest town-sized residential area is the Enderley/Fairfield neighbourhood with its 9,642 residents (2.86 km2 = 3,372 ppkm2). Hillcrest/Greensboro combined has 9,555 people, surrounding the university campus (with a total area of 2.35 km2 meaning there is a density of 4,059 ppkm2). Melville / Deanwell with its very high number of schools and dairies supports a population of 8,642 (area of 2.35 km2 = 3,680 ppkm2) and the Swarbrick/Kahikatea area has a population of 8,211 (3.27 km2 = 3,402 ppkm2).

When it comes to bench-marking density against Germany’s medium-sized cities we are pretty similar to Hamilton.  Looking to the Netherlands, my impression is that while my cousins moved to towns with lower population densities, their adult children are moving back to higher density areas in cities, and as in New Zealand, they find themselves priced out of the housing market and will often need their parents financial assistance to help them get started.
