Note 2.

The six zones are aggregations of the nine District Health Authorities (DHA). Zones 1, 3 and 4 are each comprised of two DHAs. The remaining three zones change in name only with the following small exception. Mount Uniacke area, previously part of Zone 3 is cut-off by new DHA 4 boundary. Statistics for this area (population 1,114) will be included with DHA 9 (Halifax area). As a result, there is high comparability between Zone 6 and DHA 9 and between Zone 3 and DHA 4/5.
Zone 1 = 1211 District Health Authority (DHA) 1, 1212 District Health Authority (DHA) 2
Zone 2 = 1213 District Health Authority (DHA) 3
Zone 3 = 1214 District Health Authority (DHA) 4, 1215 District Health Authority (DHA) 5
Zone 4 = 1216 District Health Authority (DHA) 6, 1217 District Health Authority (DHA) 7
Zone 5 = 1218 District Health Authority (DHA) 8
