Lesson 4: Residential Segregation & Socioeconomic Disparities
Reading socioeconomic difference as a spatial pattern with identifiable causes.
🎯 Ngā Whāinga Akoranga | Learning Intentions
Spatial variation in residential housing density, median income, decile ratings, and ethnicity across urban suburbs (e.g. Herne Bay vs Otara).
Analyse census spatial data maps, calculate index of deprivation trends across meshblocks, and explain the socioeconomic processes driving spatial segregation.

Socioeconomic Spatial Patterns & Segregation
Video Clip: Urban sprawl and suburban growth patterns (watch 0:00–9:20 of a 12m 00s video).
🧠 1. Before Viewing (Activate & Predict)
How do market forces, historical redlining, and housing costs create distinct rich and poor neighbourhoods in urban centres?
👁️ 2. During Viewing (Watch With a Job)
- Heads up — this clip is a United States example. Watch it for the general process of suburban growth and sorting, not for Aotearoa data. The census meshblock and state-housing work happens in the activity below, using New Zealand sources.
- Pause @ 1:40: Note how the clip describes growth pushing outward from the centre. What is driving the outward push?
- Pause @ 3:20: Note which groups are described as able to move outward, and which are not. Who has the choice?
- Pause @ 4:45: Note what the clip says government policy did to the pattern — then ask what the New Zealand equivalent would be.

Immediate Task: Complete Section 4 of your Geography Portfolio: NZ Deprivation Index Spatial Analysis & Suburb Comparison.
⚡ Whakaoho | Do Now: Predict the Difference, Then Check It
Two suburbs at opposite ends of the same city. Before you touch any data: write down four things a census could measure that would differ between Herne Bay and Ōtara. Measurable things, not opinions.
Then write one sentence on what caused the difference. Today you test both against real meshblock data — and the causes will matter more than the numbers.
📖 Activity 1: Read the Choropleth, Then Explain It
Get the numbers (13 min). Using the census meshblock maps, record median income, housing tenure (owned against rented) and household size for four suburbs across the isthmus. One table, source named.
Explain, do not just describe (12 min). For every gap you found, write the process that produced it — where state housing was historically built, what coastal land costs, who the transport network serves, how lending decisions were made. A pattern with no process behind it is half an answer, and it is the half that stops at Achieved.
📝 Activity 2: Level 2 Geography Portfolio Task & Merit/Excellence Scaffolding (20 mins)
Portfolio Section 4. Submit: (1) your four-suburb data table with the source named; (2) a deprivation-index trend statement backed by two specific figures; (3) one paragraph explaining a socioeconomic process that produced the spatial pattern — written in terms of people's decisions and the constraints they faced, not in terms of suburbs being good or bad.
