Examining Demographics of an Address/Locale

.. the word is that Bosch lives in a different census block and block group than in 2010. He didn’t move. How could this be? Suppose he knows? And why it matters?
.. using VDA Web GIS, here we explore the Find Address feature to locate and view addresses/locations and examine demographic-economic characteristics of the associated locales.
.. the popular Amazon Bosch TV series uses a filming location located at 7207 Woodrow Wilson Dr, Los Angeles, CA 90068 .. one U.S. residential address among the more than 141 million in the U.S. While this location has Census 2010 block code 06-037-140700-2005, the Census 2020 block code is 06-037-140700-1007 .. not only a different block but different block group (Census 2010: BG 2, Census 2020: BG 1). Analysts, and ultimately decision-makers, need to examine  BG/block pdemographics to compare 2010-based data with 2020-based data to understand patterns and trends.

.. the total number of housing units in the U.S. grew by 6.7% between 2010 and 2020 (140,498,736 based on Census 2020) — approximately half the rate of growth during the previous decade.
