GLOSSARY
Employed people living in region Employed people living in region (in the Interactive maps and data cubes) refers to the number of employed people living in a region, excluding those who commuted 250 km or more or those with nonspatial geographies. Employed people working in region Employed people working in region (in the Interactive maps and data cubes) refers to the number of employed people working in a region, excluding those who commuted 250 km or more or those with nonspatial geographies. Interquartile range The interquartile range is the difference between the upper and lower quartiles and describes the middle 50% of values when ordered from lowest to highest. Quartiles divide an ordered dataset into four equal parts and refer to the values of the point between the quarters. The upper quartile is the point between the lowest 75% and highest 25% of values (also called the 75th percentile). The lower quartile is the point between the lowest 25% of values and the highest 75% of values (25th percentile). In this publication, this statistic excludes people who commuted 250 km or more and includes those who commuted nil distance. Median commuting distance This is the level of commuting distance which divides the units in a group into two equal parts, one half having distance above the median and the other half distances below the median. In this publication, this statistic excludes people who commuted 250 km or more and includes those who commuted nil distance. Mode of travel to work The Mode of Travel to Work (MTW06P, MTW15P) is a variable derived from the Census item Method of Travel to Work (MTWP) which records the method used to travel to work on the day of the Census. Each commuter is only counted once based on their first response on the Census form, even if they reported multiple modes of transport. For example, if their method of travel to work was 'Train, ferry' they were placed in the count for the Train category but not for the Ferry category. Net effect Net effect is the sum of net flows from a location to all other regions, or in other words, the total of all inflows minus the total of all outflows for a single region. Net flows Net flows are the total inflow minus the total outflow between two specified regions. Percent of commutes Percent of commutes (in the Journey to Work interactive maps) represents the percentage of employed people commuting to or from the selected SA2, for other SA2s on the map. Place of Usual Residence This is the place where a person usually lives. It may, or may not be the place where the person was counted on Census night. Place of Work Place of Work data provide information on the address of the person's workplace in the week prior to Census night. Private transport Private transport refers to people whose mode of travel to work on Census day was car (as driver or passenger), truck or motorbike/scooter. Public transport Public transport refers to people whose mode of travel to work on Census day was train, bus, ferry, tram or taxi. Rank Rank (in the Journey to Work interactive maps) represents the top commutes associated with the selected SA2. Selfcontainment Selfcontainment is when a person's place of work was in the same SA4 as their place of usual residence. Special Purpose Codes Special Purpose Codes allow address data to be coded to a nonspatial value. This occurs when there is insufficient information to code to a physical geographic area. For example, when someone is in transit on Census night or where an incomplete address has been supplied. Standard deviation Standard deviation measures the spread of data around the mean. It summarises how close each observed value is to the mean. Groups with a small spread of values are very close to the mean, resulting in a small standard deviation. Groups with more dispersed values are spread further away from the mean, leading to a larger standard deviation. In this publication, this statistic excludes people who commuted 250 km or more and includes those who commuted nil distance. Document Selection These documents will be presented in a new window.
