Not that much smaller:<p><pre><code>                   Population    Killed
                   (mid-2012)    by Police
  United States    314,102,623     984
  England &amp; Wales   56,567,800       3
  Ratio                     6x    328x

Don&#x27;t think land area makes sense. However adjusting for crime rates and demographics would make a big difference.
