The animated map below shows a year’s worth of my mobile phone data obtained from my mobile operator, Three.

Every point that appears on the map is a phone call I made or text message I sent, with the location derived from the handset’s distance from the nearest antenna masts.

The biggest outliers are Russia, Norway and the US, with below average life in relation to GDP per capita. Read more

British graduates today are saddled with debt and have starting salaries below those of the pre-recession cohort. To make matters worse, those who secure a highly sought-after job in central London will struggle to find an affordable room to rent unless they move out to the suburbs and take on a lengthy commute.

Find out how affordable different properties are at different salary levels across London using the interactive map below, which was made using data provided by Hometrack.

Gentrification and commercial developments are breaking up Chinatowns in US and British cities, squeezing Chinese communities out of the vibrant neighbourhoods that grew up around earlier generations of migrants.

The changing demographics of New York City further highlight this pattern, with Asian communities having sprung up in Flushing and Queens, where they were traditionally focused in Lower Manhattan.

Wokingham is the top area in Great Britain for technology jobs, with the silicon sector accounting for more than five times as large a share of its labour market than the national average.

According to a report compiled by data firm Markit for KPMG, the south east of England is host to almost two in every five local authorities with technology employment location quotients (LQs) greater than 1.0, indicating that tech jobs comprise a larger proportion of the local job market than the equivalent figure across England, Wales and Scotland.

One of the ways DECC achieves its net savings figure is by assuming sizeable energy efficiency savings over the coming decades. By 2030, the document projects efficiency savings equivalent to 5 per cent of what the typical dual fuel bill would be were the policies not put in place.
