Re: 1350 Boylston
^so how long will it take Boston to pass its high score of 800,000+ people from the 50's?
Time fore a little math.
There were 272,481 total housing units in the city in 2010, 92.7% of which were occupied, but overall the average household size was 2.26.
Researchers from Northeastern's School of Urban and Regional Policy have said that Boston needs to add 10,000 units to 20,000 units annually for the next decade to remain economically competitive. With the number of units approved around the city in the last year, it appears Boston could be close to hitting the low end of that annual target for the first time since the 1980's. By the average household size multiple (2.26) and a rate of 10,000 new units target, that would mean nearly 22,600 new residents added annually; however, the average household size continues to decline, so let's be more conservative and estimate in the most optimistic of circumstances that it would be closer to 20,000 new residents annually.
2010: 617,594
2012: 636,479
So beginning in 2013...
2013: 655,000
2014: 677,500
2015: 699,000
2016: 720,000
2017: 740,000
2018: 760,000
2019: 780,000
2020: 800,000
^^This population growth scenario assumes every NIMBY became a YIMBY, the BRA expedited the approval/permitting process, and developers became more ambitious with their development proposals.
REALITY
The official population of Boston after the 2010 US Census was 617,594 people. According to wikipedia, the city had a 2012 population of 636,479. That would mean Boston added an average of 9,441.5 people per year.
Assuming Boston keeps this momentum, the new mayor is development friendly, and market demand remains constant, Boston will likely see population growth like this over the coming years:
2012: 636,479
2013: 647,000
2014: 657,500
2015: 668,000
2016: 679,500
2017: 691,500
2018: 704,000
2019: 716,500
2020: 729,500
2021: 743,000
2022: 757,000
2023: 771,500
2024: 786,500
2025: 802,000
So again, Boston has a real shot at regaining its 1950's population by the year 2025 if it continues with its current momentum.
