Data Visualization of Cultural Demographics

Cultural Context

This activity uses published demographic data from Aotearoa New Zealand to explore how statistical representations can help us understand our diverse population. We acknowledge the importance of accurate representation of all cultural groups, particularly Māori as tangata whenua.

Source: Stats NZ, 2018 Census ethnic group counts (total response). Kaiako: 2023 Census results are now published — check Stats NZ for current figures before teaching, and have ākonga compare the two if you can.

Learning Objectives

Activity 1: Exploring NZ Cultural Demographics

Use the following data from the 2018 New Zealand Census to complete the activities:

Before you start — these percentages add up to more than 100%, and that is not a mistake. Stats NZ records ethnicity as total response: a person who identifies as both Māori and European is counted in both rows. So you cannot put this straight into a pie chart, because a pie chart assumes the parts sum to the whole. Deciding what you can honestly draw from this table is the first task.

Ethnic Group	Population	Percentage of Total
European	3,297,864	70.2%
Māori	775,836	16.5%
Pacific Peoples	381,642	8.1%
Asian	707,598	15.1%
Middle Eastern/Latin American/African	70,332	1.5%
Other	54,819	1.2%

Task 1: Choosing the Right Visualisation

For each research question below, select the most appropriate type of data visualisation and justify your choice:

How does the Māori population compare to other ethnic groups in New Zealand?
How has the proportion of Asian New Zealanders changed over the last 3 censuses?
What is the geographic distribution of Pacific peoples across New Zealand regions?

Task 2: Create Your Visualisations

Using digital tools (Google Sheets, Excel, or online chart makers), create three different visualisations of the data above. For each visualisation:

Include all necessary labels and titles
Choose appropriate colours that are culturally respectful
Write a 50-word interpretation of what the visualisation shows

Note: For students using screen readers, describe your visualisation choices in detail and provide text alternatives for any images created.

Activity 2: Critical Analysis

Examine these two visualisations of the same data:

Visualisation 1: Pie chart with all ethnic groups shown equally

Image description: A pie chart showing ethnic group proportions with equal slice sizes despite different population percentages.

Visualisation 2: Bar graph with accurate proportional representation

Image description: A bar graph accurately showing population numbers for each ethnic group with proper scaling.

Discussion Questions:

How does each visualisation affect your understanding of the data?
What ethical considerations should we keep in mind when visualising demographic data?
How might the choice of visualisation impact decision-making by government or community groups?
Why is it important to accurately represent Māori demographic data in particular?

Cultural Safety Considerations

Ensure all ethnic groups are represented with respect and accuracy
When discussing Māori data, acknowledge the unique status of Māori as tangata whenua
Be aware that some students may identify with multiple ethnic groups
Approach discussions about demographic changes with sensitivity
Use official Statistics New Zealand data sources for accuracy

Extension Activities

For Advanced Students:

Research and compare demographic data from the 2013 and 2018 censuses. Create an animated visualisation showing changes over time.
Investigate how demographic data is used in the Māori Electoral Option process. Create an infographic explaining this to younger students.
Analyse how different media outlets visualise the same demographic data. Write a report comparing their approaches and potential biases.
Create an interactive dashboard using real NZ census data that allows users to explore different demographic combinations.

Assessment Suggestions

Teacher Implementation Guide

Criteria	Achieved	Merit	Excellence
Data Visualisation Accuracy	Creates basic visualisations with some errors	Creates accurate visualisations with appropriate formats	Creates sophisticated, accurate visualisations with insightful formatting choices
Cultural Consideration	Shows basic awareness of cultural representation	Demonstrates good understanding of cultural representation needs	Shows sophisticated understanding and application of culturally appropriate representations
Critical Analysis	Identifies basic differences in visualisations	Analyses how visualisation choices affect interpretation	Provides insightful analysis of visualisation impacts with reference to cultural contexts

Before the Lesson:

Familiarize yourself with the latest demographic data from Stats NZ
Prepare digital tools students will use (Google Sheets, Excel, etc.)
Create example visualisations to show different approaches
Identify students who may need additional support

During the Lesson:

Introduction (15 mins): Discuss why demographic data matters in NZ, particularly for Māori development and resource allocation
Activity 1 (40 mins): Guide students through creating their visualisations, circulating to provide support
Activity 2 (30 mins): Facilitate discussion about visualisation choices and cultural considerations
Wrap-up (15 mins): Have students share one insight about how data visualisation affects understanding of cultures

Adaptations:

For visual impairments: Provide tactile graph materials or focus on descriptive statistics
For ESL students: Provide vocabulary lists and sentence starters for discussions
For extension: Offer access to additional census datasets and more advanced tools like Tableau Public
For cultural connection: Invite a local Māori data expert to discuss how iwi use demographic data
