Will your area of London be affected by the closure of ten fire stations today?
This map divides London into regions around each existing fire station. In areas shaded dark red, the nearest fire station will be closed. In regions shaded lighter red, the local station will lose a fire engine or specialist rescue unit. In blue-shaded regions, the nearest fire station will gain an additional fire engine.
Twitter is going public and has been valued at up to $17.4bn, but that could be low as the company could be trying to achieve a large IPO pop once its shares start trading. But what do you think it is worth? What assumptions would you need to make to arrive at this conclusion?

Italy goes to the polls on February 24 and 25, after Mario Monti, the country’s technocratic prime minister, announced his resignation in December. He is attempting to safeguard his legacy by standing as a campaigning politician, but Mr Monti faces strong competition.
This interactive graphic shows Italy’s economic standing and its regional disparities and what the newly elected government will have to grapple with once it comes to power.
The London Fire Brigade has published its incident data for the past four years in the London Data Store, the capital’s open data repository.
The data, originally obtained by the Financial Times under the Freedom of Information Act and published last week in our London Fire Brigade response times map, is being released as open data because of widespread interest in the potential impact of fire station closures.
The London Fire Authority is defying mayor Boris Johnson’s order to put the proposed cuts to public consultation. The £45m cut in the brigade’s budget over two years, would see 12 fire stations, 18 engines and 520 jobs go. Read more

The latest England and Wales census data throw a spotlight onto an increasingly multi-lingual population – at least where London is concerned. In the capital one in five households do not speak English as their main language. However, London is far from representative of the country as a whole.
You can use this interactive map to explore clusters of languages around the country. Choose the language in the drop down menu, then zoom into areas of interest.
The latest data from the FT/Economist Business Barometer, the quarterly global business sentiment survey, was published last week and the business-friendliness section again made for interesting reading.
France’s “business friendliness” has plummeted since the last barometer survey, which was conducted before before the election of François Hollande as president. For the first time, more of the business executives surveyed by the EIU rated the country’s ”unfriendly” than “friendly” to business. Read more

As expected, the US and China topped the conventional Olympic medal tables (however you chose to sort them). But by merely achieving the expected, the sporting superpowers appear much farther down the FT’s weighted medal table, which ranks countries by how much they exceeded pre-Games expectations.
Our table benchmarked nations performance against macroeconomic factors known to affect Olympic performance, such as GDP and population.
Great Britain’s 29 gold medals and 65 overall was enough for third place on the FT table as well as the conventional table – an impressive feat given the handicap our methodology imposed on it by taking into account the host-nation advantage. Here’s a look at some of the other nations that can leave London extremely happy, having greatly exceeded expectations. Some of them may surprise you. Read more
This scatterplot below shows how nations’ actual medal performance at London 2012 compares to the economic models used to construct the FT medal table, along with some of the underlying factors used by the models, such GDP, population and performance at Beijing in 2008.
How does Great Britain’s haul of 65 medals, including 29 golds, compare to other recent host nations’ performance?
There can be little doubt that greater recent investment in elite sports is the main cause of Great Britain’s impressive performance at these Olympics an uptick in performance compared with Beijing 2008 would have been expected regardless, because of a well-documented “host-nation effect” that sees the home team performed significantly better than it usually does.

We launched the FT’s economically-weighted medal table on Sunday night.
Rather than ranking the table in the conventional format – gold medals followed, where equal, by silver medals and finally bronze medals – we are ranking counties by their performance against a benchmark developed from four economic models. These predict success on the basis of socioeconomic factors that have been shown to contribute to Olympic performance historically.
Even on our weighted measure, China leads with its 12 medals, representing 4.6 more than would be expected at this stage of the games. Italy’s seven medals place its over-achievement to date hundredths of a percentage point behind. Great Britain, by contrast, is near the foot of our table, underachieving by 2.8 medals so far.

Over the next two weeks, the Olympic “medal table”, ranking nations according to the number of gold, silver and bronze medals their athletes have collected in London will be widely reported.
But there will be few surprises: The United States, China and Russia will almost certainly top the table, followed by the smaller wealthy countries. Great Britain will most likely fare better than usual, because the host nation usually does.
Population, GDP per capita, past performance and “home advantage” appear to have a strong relationship to nations’ Olympic success, a common-sense observation that has long been demonstrated by social science.
Substantial academic literature, stretching back to the 1950s, has been produced by economists, sociologists and political scientists using statistical techniques to relate nations’ macroeconomic conditions to their Olympic performance, and forecasting upcoming games.
Typically, these take the form of regression analyses that use historical macroeconomic data as independent variables to account for participating countries’ medal share at the Olympics.
During the London games, the FT will use
three four such models as a benchmark to rank our medal table according to teams’ ability to outperform models that account for their size, wealth and other socioeconomic factors: Read more
The population of England and Wales has grown by more than seven per cent since 2001, the first release of data from the 2011 census shows.
The estimate, based on the census taken on March 27 2011, recorded a population of 53.0 million in England and 3.1 million in Wales, representing an increase of 3.7 million in the decade since the 2001 census, which recorded a population of 52.4 million.
This increase of 7.1 per cent represents the largest growth in the population in England and Wales in any 10-year period since the 1911 census.
With more than a year’s worth of of data from our exclusive business sentiment poll, the FT/Economist Global Business Barometer, now available, some interesting longitudinal patterns are becoming apparent for the first time.
Most notable among them is the steady erosion over the past year in executives’ perceptions of the “business friendliness” three of the world’s biggest developing economies, India, China and Brazil.
What we’re reading today in the world of statistics, open data and data journalism:
We like a good political choropleth around here, and Sunday’s European election extravaganza did not disappoint in the psephological cartography department.
A good map of the Greek results can be found at igraphics.gr, Le Monde has the obligatory map of the French presidential election par département, and Michael Neutze’s site Wahlatlas covered the results in the German state of Schleswig-Holstein. Read more
