Twitter and Foursquare data shows where the well-to-do are likely to move next. Do you dread the thought of gentrification jacking up real estate prices (and stifling culture) in your neighborhood? In the future, you might only need to keep tabs on social networks to know when your part of town is changing -- British researchers have learned that Foursquare check-ins and Twitter posts can help predict gentrification. If many people start visiting unfamiliar locations in materially-deprived neighborhoods (say, trendy new restaurants) with their friends, that's usually a good sign that these areas will be gentrified before long. Accordingly, places that are dominated by locals and regulars tend to resist that shift, no matter the income levels. Moreover, the very people who tend to use Foursquare and Twitter work to the advantage of this predictive model. The researchers believe that the people who most often use these networks tend to be the affluent types who create gentrification. The very fact that they're showing up in a given region, however temporarily, may be proof enough that demographics are changing. There's only been a limited amount of testing so far, but it's promising. The check-ins and tweets accurately predicted the gentrification of London's Hackney area in recent years, and they've already identified a few additional areas (Greenwich, Hammersmith, Lambeth and Tower Hamlets) that could be next. Provided this method holds up, it could give communities a chance to mitigate the negative effects of gentrification before it's too late, such as by working on affordable housing. http://www.engadget.com/2016/04/18/predicting-gentrification-through-tweets/ -
STATISTICS CANADA April 20, 2015 1:34 pm People in Vancouver and Toronto least satisfied with their lives: StatsCan Man under umbrella in Vancouver Vancouverites report being less satisfied with their lives than residents of other Canadian cities, according to Statistics Canada. Maybe it's the rain? Jonathan Hayward / The Canadian Press Residents of Vancouver and Toronto report being less satisfied with their lives than people in other Canadian metropolitan areas, according to a new study published by Statistics Canada. Researchers asked the residents of various census metropolitan areas to rank their overall life satisfaction on a scale of 0 to 10, where 0 was “very dissatisfied” and 10 was “very satisfied.” In Vancouver, the average score was 7.808, followed closely by Toronto at 7.818. People living in Canada’s most-satisfied metropolitan area, Saguenay, gave an average score of 8.245 out of 10. The differences are larger when you look at the percentage of people who rate their life satisfaction as a 9 or 10 out of 10. In Sudbury, 44.9 per cent of residents ranked their overall life satisfaction that high. In Vancouver, it was only 33.6 per cent. When it comes to people who were comparatively unsatisfied with their lives – giving themselves a score of only 6 or less, there are again significant differences between cities. 17.1 per cent of people in Windsor, Toronto and Abbotsford-Mission ranked their life satisfaction at a 6 or less. Only 8.6 per cent of people in Saguenay gave themselves such a low score. To figure out what accounts for the differences, researchers tested various hypotheses. They found that people who are married or are in good health tend to rank their life satisfaction much higher than others. Unemployed people are more likely to have low satisfaction, and richer people higher satisfaction. However, the report states, these personal factors don’t seem to account entirely for the variation across metropolitan areas. The researchers note that smaller communities with a population of less than 250,000 tend to report higher average life satisfaction. Also, when sorted by city size, metropolitan areas in Quebec tend to be at the top of the list: Montrealers are the most satisfied among individuals in Canada’s big cities and most likely to report life satisfaction of 8 or higher, Sherbrooke and Quebec are at the top of the mid-size communities, and Saguenay and Trois-Rivières at the top of the smaller metropolitan areas, according to the study. Although the Statistics Canada researchers don’t definitively say why this is, they point to other research that suggests levels of trust and social connections in local communities have an effect on people’s life satisfaction, as does income relative to one’s neighbours and economic inequality. sent via Tapatalk
