Mirrors morie_tps_csi_per_year but groups by
neighbourhood ID rather than fiscal year. Population is not divided
in here because TPS open data does not ship a per-ward population
table; callers are expected to merge in the City of Toronto Open
Data NeighbourhoodCrimeRates per-ward population for per-capita
rates. Returns the un-normalised weighted sum + total count.
Usage
morie_tps_csi_per_neighbourhood(
counts_per_hood,
variant = c("total", "violent"),
weights = NULL
)
