Pollution Equity in London

A Brief Description
These datasets are obtained from the London Datastore each one relates to a kind of pollution - either potentially problematic materials in the air, or levels of noise.

These measure daily average decibel levels for road- and rail-originated noise in London. In addition, the file pm25.csv gives average levels of PM2.5 per Output Area (OA) in London. OAs are the smallest geographical census units in the UK is the concentration of solid particles and liquid droplets with a diameter less than 2.5 micrometres, and is thought to be the air pollutant which has the greatest impact on human health.

Finally the file LOAC.geojson contains a map layer with the boundary each of the OAs in London, together with their OAC (output area classification). The OAC is a geodemographic classification applied to each OA used to describe the social and economic composition of its population. There are three levels of detail for the classification: Supergroup, Group and Subgroup with column names Sub,Group and Super. Typical examples of the codes are:

Supergroup H (Urban Settlements) : The areas are characterised by a slightly younger age structure than nationally, with higher proportions of all groups aged 45 and under (covering the age groups 0 to 4 years, 5 to 14 years and 25 to 44 years). Ethnic groups are over-represented compared with the national picture and households are more likely to live in semi-detached or terraced housing.

Group H2 (Suburban Traits) : This group has a higher proportion of people aged 25 to 44 years than the supergroup and a higher proportion have Chinese, Black, African, Caribbean or Black British ethnicity, and are likely to live in flats.

Subgroup H2a (City Periphery) : The subgroup has a slightly older age profile than its parent group and a larger proportion were born in the UK. Residents are more likely to live in a terraced property or flats.
