  • Somerville Housing Over Time

    September 5th, 2019
    housing, somerville  [html]
    I wanted to understand how the number of housing units in Somerville had changed over our history, but wasn't able to find anything searching online. We can get an estimate, however, by looking at the "Year Built" field in the Assessor's Database. This shows the age of Somerville's current housing stock, to the best estimate of the Assessor.

    Decade Number Built
    17xx 7
    180x 36
    182x 3
    183x 1
    184x 30
    185x 65
    186x 79
    187x 143
    188x 476
    189x 1025
    190x 4657
    191x 1863
    192x 2104
    193x 401
    194x 55
    195x 75
    196x 104
    197x 181
    198x 394
    199x 72
    200x 24
    201x 51 (57 projected)

    In estimating how much building was happening in various decades this will be biased towards the present: a building that was demolished and replaced will show up as being built recently, replacing the earlier older listing. On the other hand, newer projects are often larger, as former industrial sites are converted to housing. Still, it shows that current building levels in Somerville, while higher than in the 2000s, are still very low by historical standards.

    (The most recent year I see in the data is 2018, so I've scaled the numbers for the 2010s decade up by 10/9 to reflect that we're missing 2019 data. I've also truncated the data to just the decade because my understanding is it's common for the database to use the first year as a stand in for "some time that decade", with 1910 to mean 1910s. Only 11,847 of the 12,145 parcel records contain a "Year Built" field so I'm ignoring the other 2%. I'm also ignoring 84 Perkins St, parcel 14057, which claims to have been built in 1518.)

    People frequently1 think that I'm very stupid. I don't find this surprising, since I don't mind if other people think I'm stupid, which means that I don't adjust my behavior to avoid seeming stupid, which results in people thinking tha…

    Experiences in raising children in shared housing

    Sometimes I see posts about people’s hope to raise children in a group housing situation, and it often seems overly optimistic to me. In particular they seem to expect that there will be more shared childcare than I think should be expected. Today I talke…
