Bonds lodged for rental properties in the Central Hawke's Bay District, New Zealand

Closed bonds represent the number of tenancy agreements from that month that have ended.

Geometric mean: The geometric mean is calculated by multiplying n values together and taking the nth root of the result. When a variable is log-normally distributed (a common distribution for variables than must be greater than 0) the geometric mean will closely approximate the median.
Synthetic Quartiles (replacing quartiles): The synthetic quartiles are designed to find the 25th percentile (for the lower quartile) and 75th percentile (for the upper quartile) of a set of data, assuming the data is lognormally distributed. The mean and variance of the data are not assumed, but instead are calculated. This approach is consistent with using the geometric mean to approximate the median.

The files include the private bonds, starting from January 1993. 'Private' means private sector landlords.
