A more interesting indicator that authors may consider is how many people living in the area do jogging.<p>When I moved to London&#x27;s SE4 postcode three years ago (it&#x27;s pretty close to Peckham, FWIW), the regeneration of the area has just started and the more middle-class looking people appeared around, the more men and women in running gear were visible in the streets in the morning. Poor on average take worse care of their health and fitness, so tapping into Runkeeper&#x27;s data may prove useful.<p>In the meanwhile, during these three years, the value of my home grew more than 100%.
