In this unit, students learn what vital statistics are, and that Statistics New Zealand collects and collates these data. The focus is for students to present and communicate a chosen aspect of population statistics in the most appropriate graphic way, and to explain and justify their choice of visual display.
The focus of level 3 investigations typically expands from students exploring information about themselves and their immediate world, to exploring information in, and about, the wider world.
Accordingly, in this unit, students develop an understanding of vital statistics (quantitative data concerning the population, such as the number of births, marriages, and deaths), of where these can be located, of how useful and interesting they can be, and how best to represent these data visually.
As students are exposed to a range of population data they should select data of particular interest to them, and consider and choose the visual data display that would best present the numeric information.
Within this, students will apply their knowledge and experiences, developed during Level 2, of frequency tables, bar graphs, strip graphs, and pie charts for category data; dot plots and stem and leaf graphs for whole-number data; and simple line graphs for time series data.
Students should use computer technology to create these displays, to find patterns, to communicate their findings to others, and to justify choice of display/s.
The Department of Internal Affairs registers births, deaths and marriages (BDM) and maintains NZ birth, death, marriage, civil union and name change information, and issues certificates and printouts.
The registration number is a unique number allocated to every registered birth, death, marriage or civil union,
Information on the number of births and deaths registered in New Zealand is published once a year: https://www.stats.govt.nz/topics/births-and-deaths
Statistics on the number of marriages, civil unions, and divorces registered in New Zealand is also released annually: https://www.stats.govt.nz/topics/marriages-civil-unions-and-divorces
The learning opportunities in this unit can be differentiated by providing or removing support to students, or by varying the task requirements. Ways to support students include:
The activities in this unit can be easily adapted to draw on the interests and experiences of your students. Instead of investigating name data for their own birth year, and for that of a parent or grandparent, students could investigate name data for the birth year of a favourite sports person or historical figure that they are currently learning about. Consider how this context might relate to your students' interests, cultural backgrounds, and their learning from other curriculum areas.
Te reo Māori kupu such as ōrau (percent) and tūhuratanga tauanga (statistical investigation) could be introduced in this unit and used throughout other mathematical learning.

Individually or in pairs:
Dear Parents and Whānau,
This week in maths we are reading statistical data about New Zealand’s population.
Ask your child what are some of the interesting facts they have learned. You might like to investigate together the data available here, including finding out if your name was in the list of most popular names for your birth year.
