A competition encouraging Kiwis to create cool visualisations with census data has just been launched, Stats NZ said
The competition encourages people to create a cool, interactive visualisation of 2018 Census data about the way people
commute to work and education – this data was released today. A prize of $5,000 is on offer for the winner, and Stats NZ
will promote and share the winning entry.
“This is an opportunity for data and geospatial enthusiasts to showcase their innovation and skills using 2018 Census
data,” general manager social and population insights Jason Attewell said. “We’ve left this as open to the imagination
as possible and we’re really excited to see what people come up with.”
The competition will run from 17 June until 15 July and is open to any New Zealand resident who isn’t an employee of
Stats NZ. The winning visualisation will be announced on 29 July, and the winner will receive $5,000, and a link to
their product will be placed on Stats NZ’s website and promoted through Stats NZ channels.
Full information about the competition can be found on the Stats NZ website at www.stats.govt.nz/commute
. See Datafinder – commuter view
for the data.
Submissions will need to meet minimum quality and usability criteria to qualify, and entrants must agree to abide by all
Stats NZ’s terms and conditions.
In 2013, Stats NZ developed and released its own CommuterView
product using 2013 Census data. This interactive, well-used product shows how people in New Zealand travelled to and
from work. It’s a rich dataset with a lot of value for central and local government, academics, transit companies, and
other transport and city planners.
Stats NZ originally planned to develop a 2018 version itself, but time constraints relating to the work required to be
done on the 2018 dataset before it could be released have made it challenging to do so.
“Once we understood the challenges facing us, we realised what an amazing opportunity it could be to open this
visualisation development up to everyone in New Zealand,” Mr Attewell said. “I’m genuinely excited to see what people
can do with this data using their skills and experience. New Zealand is famous around the world for its creative and
innovative spirit and I’m really keen to see that in action in the entries we receive. Opening this up to see what
others can do also fits with our philosophy that census data is Aotearoa's data.”

About the 2018 Census dataset
We combined data from the census forms with administrative data to create the 2018 Census dataset, which meets Stats
NZ’s quality criteria for population structure information.
We added real data about real people to the dataset where we were confident the people should be counted but hadn’t
completed a census form. We also used data from the 2013 Census and administrative sources and statistical imputation
methods to fill in some missing characteristics of people and dwellings.
Data quality for 2018 Census
provides more information on the quality of the 2018 Census data. An independent panel of experts has assessed the
quality of the 2018 Census dataset. The panel has endorsed Stats NZ’s overall methods and concluded that the use of
government administrative records has improved the coverage of key variables such as age, sex, ethnicity, and place. The
panel’s Initial Report of the 2018 Census External Data Quality Panel
assessed the methodologies used by Stats NZ to produce the final dataset, as well as the quality of some of the key
variables. Its second report 2018 Census External Data Quality Panel: Assessment of variables
assessed an additional 31 variables.
In its third report, Final report of the 2018 Census External Data Quality Panel
, the panel made 24 recommendations, several relating to preparations for the 2023 Census. Along with this report, the
panel, supported by Stats NZ, produced a series of graphs summarising the sources of data for key 2018 Census individual
variables, 2018 Census External Data Quality Panel: Data sources for key 2018 Census individual variables
