From the appendix of the report mentioned in the no doubt well-perused article (<a href="http:&#x2F;&#x2F;www.lao.ca.gov&#x2F;Publications&#x2F;Report&#x2F;3345" rel="nofollow">http:&#x2F;&#x2F;www.lao.ca.gov&#x2F;Publications&#x2F;Report&#x2F;3345</a>):<p>&quot;&quot;&quot;We use data (.xlsx) on Bay Area census tracts (small subdivisions of a county typically containing around 4,000 people) maintained by researchers with the University of California (UC) Berkeley Urban Displacement Project. This dataset included information on census tract demographics, housing characteristics, and housing construction levels. We focus on data for the period 2000 to 2013.&quot;&quot;&quot;
