Somebody mentioned a statistic that I was surprised to hear. It said that today 70% of white collar work happens in non co-located teams. Which means people no longer work with people in the next cubicle or down the hall. This also means that people are no longer chained to their desks.
This has meant that there is more flexibility in where people choose to live and it is no longer tightly coupled with where they work. Families with kids ofcourse focus on living next to schools and neighbourhoods that are safe and good for the kids. Families with no kids, which are an increasing number year over year, locate based on their non-work related pastimes. Such people locate near theatre and art districts, outdoor getaways and urban parks.
