Christchurch has reported half a million problems.
Every one the council has published since 2015, archived here every ten minutes — because the council’s own API only ever serves today. This is the only place the past is kept.
Reporting keeps growing
Reports per year, by kind. Not necessarily more problems — more people with the app in their pocket.
Week by week
The weekly rhythm
Every report ever, by day of the week.
The daily rhythm
By hour of the day.
Some problems have a season
Reports by month of the year, every year stacked together.
Suburbs that report most
Last five years.
Spots that keep coming up
Counted by how many separate days each address was reported, so one day of bulk filing counts once.
Reporting more than it used to
Last 12 months against the 12 before. Suburbs with at least 150 reports in the earlier year.
Reporting less
The other end of the same comparison.
The worst days on record
The days Christchurch filed the most reports, and what they were about.
What people actually report
The council’s own incident types, last five years.
Archived from Christchurch City Council open data every ten minutes. Counts reflect what people reported, not everything that happened — a rise can mean more problems, or just more people reporting them. Suburb comes from a free-text address and is missing on about a third of reports.
