The 'gap' in health indicators was measured by a ratio of the rate in the low Socioeconomic status (SES) group to the rate in the high SES group. A ratio of 1.0 indicates no difference between the two groups. A ratio higher than one indicates higher rate of the disease or behaviour in the low SES group.
At the time of this resource, complete death data from Vital Statistics was only available for years up until 2007. The delay in releasing data results from the time required to ensure data quality. The delays for mortality data are longer than for other sources used in this resource, such as hospitalizations and survey data.
