Lesson 4: Residential Segregation & Socioeconomic Disparities
Demonstrating geographic understanding of urban spatial patterns, models, and processes.
🎯 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 (Runtime: 9m 20s).
🧠 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)
- Pause @ 1:40: Examine census meshblock choropleth maps displaying household income and housing tenure.
- Pause @ 3:20: Analyse how land prices near coastal/harbour views create high-income enclave pockets.
- Pause @ 4:45: Evaluate government housing policy and state housing developments in suburban spatial distribution.
🗣️ 3. After Viewing & Kaiako Move (Process & Apply)
Kaiako Move: Guide discussion on equity, manaakitanga, and public policy interventions (e.g., Kāinga Ora urban redevelopment projects).
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.
🏫 Kaiako Planning & Pedagogy Notes
NCEA Level 2 Alignment: Direct preparation for Level 2 Geography (Demonstrate geographic understanding of an urban pattern). Emphasise integrating specific case study evidence and annotated map sketches for Merit/Excellence grades.
