This paper presents data from the 2011 Census of Population and Housing for the 93 NSW State Electoral Districts (SEDs). Where available, figures from the 2006 Census have also been included. The current boundaries for the NSW SEDs were established by the 2004 Electoral Boundaries Redistribution. The next Electoral Boundaries Redistribution will take place prior to the 2015 State election. For each SED, the political party affiliation for the current Member is identified.

Each SED is profiled with details of population and other selected census characteristics. Three numbers from the 2011 Census are provided for each census characteristic:

- A count of persons/families/dwellings or a selected median/average;
- The count expressed as a percentage of the total electoral division population, or a subset of that population; and
- The electorate's rank in relation to all electorates (in most cases based on the percentage).

In many cases, the percentage provided for a census characteristic was calculated in relation to the total number of persons in the electoral district. However, for approximately half of the characteristics provided, the percentage was calculated in relation to a subset of the electoral district's total population. For example, the total number of employed persons in an electoral district is expressed as a percentage of the total number of persons in the electoral district aged 15 and over. A table showing the population used when calculating the percentage for each characteristic is provided on page 5. This follows a list of definitions set out on pages 2 to 4.

A companion Background Paper - NSW State Electoral Districts Ranked by 2011 Census Characteristics - presents the same data by census characteristic, thereby enabling easy comparison of SEDs. These two publications will be updated after the next Electoral Boundaries Redistribution.
