The icon color is greener if sector share increased in 2017 vs 2016 (red if decreased), and shape corresponds to changes over 2 years: Up triangle if share went up 2 years in a row by more than 1%, down triangle if went down 2 years by more than 1%, and circle otherwise.


Comparing to 2016 Poll: where you applied Analytics, Data Mining, Data Science in 2016?, we find the biggest increases, computed as (pct2017 - pct2016) / pct2016, were for
  • Junk email / Anti-spam, up 106%, to 2.2% in 2017 from 1.1% in 2016
  • Manufacturing, up 60%, to 9.0% from 5.6%
  • Social Good/Non-profit, up 35%, to 2.7% from 2.0%
  • Education, up 33%, to 9.4% from 7.1%

  • Supply Chain, up 31%, to 8.5% from 6.5%
  • HR/workforce analytics, up 30%, to 4.7% from 3.6%
The industries/areas with the biggest decline in share of applications were
  • Mobile apps, down -59%, to 1.3% from 3.3%
  • Investment / Stocks, down -45%, to 3.4% from 6.2%
  • Security / Anti-terrorism, down -42%, to 1.6% from 2.7%
  • Entertainment/ Music/ TV/ Movies, down -32%, to 2.7% from 4.0%
  • Telecom / Cable, down -30%, to 5.8% from 8.3%
It is very interesting that the average number of industries/areas per voter was 2.7, the same as in 2016 and only slightly different than 2.65 in 2015. Perhaps there is a limit to effective application of Data Science across industries?

In this poll we had 446 participants, compared to 552 in poll on 2016 applications, and 350 for 2015 poll.

The three-year comparison shows relative stability in share of applications for most of areas and also an increasing diversity of applications.

Only 2 sectors showed increase of 10% or more for 2 years in a row:
  • Junk email / Anti-spam
  • Fraud Detection
and only 2 areas declined in share by about 10% or more 2 years in a row:
  • Oil / Gas / Energy
