In 2010, I published this blog post entitled “Calling 911: What Humanitarians Can Learn from 50 Years of Crowdsourcing.” Since then, humanitarian colleagues have become increasingly open to the use of crowdsourcing as a methodology to both collect and process information during disasters. I’ve been studying the use of twitter in crisis situations and have been particularly interested in the quality, actionability and credibility of such tweets. My findings, however, ought to be placed in context and compared to other, more traditional, reporting channels, such as the use of official emergency telephone numbers.
So I did some digging and found the following statistics on 911 (US) & 999 (UK) emergency calls:
- “An astounding 38% of some 10.4 million calls to 911 [in New York City] during 2010 involved such accidental or false alarm ‘short calls’ of 19 seconds or less — that’s an average of 10,700 false calls a day”. – Daily News
- “Last year, seven and a half million emergency calls were made to the police in Britain. But fewer than a quarter of them turned out to be real emergencies, and many were pranks or fakes. Some were just plain stupid.” – ABC News
I also came across the table below in this official report (PDF) published in 2011 by the European Emergency Number Association (EENA). The Greeks top the chart with a staggering 99% of all emergency calls turning out to be false/hoaxes, while Estonians appear to be holier than the Pope with less than 1% of such calls.
