Noise complaints filed at NYC’s  311 in each of the last four years:

  • 2010 = 86, 364
  • 2011 = 92, 083     up 6.6%
  • 2012 = 101, 392   up 10.1%
  • 2013 = 107, 931   up 6.4%
  • 2014 = 145, 465   up 34.8%

The spike could be because of a spike in noise, a spike in the number of New Yorkers filing complaints (instead of giving up on it as a futile exercise), or a bit of both. See the previous post for other speculation why the number might have spiked.
