Custom Age Range Tool

An Excel tool is available that uses Single year of age data that enables users to select any age range required.

ONS policy is to publish population estimates rounded to at least the nearest hundred persons. Estimates by single year of age, and the detailed components of change are provided in units to facilitate further calculations. They cannot be guaranteed to be as exact as the level of detail implied by unit figures.

Estimates are calculated by single year of age but these figures are less reliable and ONS advise that they should be aggregated to at least five-year age groupings for use in further calculations, onwards circulation, or for presentation purposes. (Splitting into 0 year olds and 1-4 year olds is an acceptable exception).

ONS mid-year population estimates data by 5 year age groups going all the way back to 1981, are available on the NOMIS website.

Update 29-04-2020: The data is now split into two files based on the variable collection frequency (monthly and yearly). Additional variables added: area size in hectares, number of jobs in the area, number of people living in the area.

Context

I have been inspired by Xavier and his work on Barcelona to explore the city of London! 🇬🇧 💂

Content

The datasets is primarily centered around the housing market of London. However, it contains a lot of additional relevant data: - Monthly average house prices - Yearly number of houses - Yearly number of houses sold - Yearly percentage of households that recycle - Yearly life satisfaction - Yearly median salary of the residents of the area - Yearly mean salary of the residents of the area - Monthly number of crimes committed - Yearly number of jobs - Yearly number of people living in the area - Area size in hectares

The data is split by areas of London called boroughs (a flag exists to identify these), but some of the variables have other geographical UK regions for reference (like England, North East, etc.). There have been no changes made to the data except for melting it into a long format from the original tables.

Inspiration

The dataset lends itself for extensive exploratory data analysis. It could also be a great supervised learning regression problem to predict house price changes of different boroughs over time.

This dataset contains information on antibody testing for COVID-19: the number of people who received a test, the number of people with positive results, the percentage of people tested who tested positive, and the rate of testing per 100,000 people, stratified by borough of residence. These data can also be accessed here: https://github.com/nychealth/coronavirus-data/blob/master/totals/antibody-by-boro.csv

This table shows whether people aged 16 or over have ever used or never used the internet by a range of variables such as age, ethnicity, pay, occupation, qualifications, and disability. The question asked in the Labour Force Survey is "When did you last use the internet?" This question is only asked to people aged 16 and over. The first time this data was available was 2011 Q1. At borough level the data showed ever used or never used. For London and Rest of UK the data is broken down by a range of indicators, including age, ethnic group, weekly pay, occupation levels, qualification levels, and economic activity. The APS sampled around 333,000 people in the UK (around 27,000 in London). As such all figures must be treated with some caution. Data was supplied directly by ONS under request from the Greater London Authority. Numbers rounded to the nearest thousand. Other Internet Access data can be found on the ONS website. This is national data based on the Opinions and Lifestyle Survey.

Daytime population - The estimated number of people in a borough in the daytime during an average day, broken down by component sub-groups.

The figures given are an average day during school term-time. No account has been made for seasonal variations, or for people who are usually in London (resident, at school or working), but are away visiting another place.

Sources include the Business Register and Employment Survey (BRES) (available under license), Annual Population Survey (APS), 2011 Census, Department for Education (DfE), International Passenger Survey (IPS), GB Tourism Survey (GBTS), Great Britain Day Visit Survey (GBDVS), GLA Population Projections, and GLA Economics estimates (GLAE).

The figures published in these sources have been used exactly as they appear - no further adjustments have been made to account for possible sampling errors or questionnaire design flaws.

Day trip visitors are defined as those on day trips away from home for three hours or more and not undertaking activities that would regularly constitute part of their work or would be a regular leisure activity.

International visitors – people from a country other than the UK visiting the location;
Domestic overnight tourists – people from other parts of the UK staying in the location for at least one night.
All visitor data is modelled and unrounded.

This edition was released on 7 October 2015 and replaces the previous estimates for 2013.

GLA resident population, 2011 Census resident population, and 2011 Census workday populations (by sex) included for comparison.

Of the five boroughs of New York City, Stanten Island has the highest rate of coronavirus cases per 100,000 people. Brooklyn – the most populous borough – has around 36,008 cases per 100,000 people, and only Manhattan has a lower case rate.

Brooklyn hit hard by COVID-19 Towards the middle of December 2022, there had been almost 6.37 million positive infections in New York State, and Kings was the county with the highest number of coronavirus cases. Kings County, which has the same boundaries as the borough of Brooklyn, had also recorded the highest number of deaths due to the coronavirus in New York State. Since the start of the pandemic in the U.S., densely populated neighborhoods in Brooklyn and Queens have been severely affected, and government leaders across New York State have had to find solutions to some unprecedented challenges.

All ages total includes some cases where the age was not known. Therefore the age groups may not add to the total. Regional totals are estimated to take account of missing data.

Dash ("-") means a local authority was unable to submit details on the number of people registered as being deaf and hard of hearing.
