Looking on the Intel website, it looks like the latest 32-bit atom processor they released was in 2011 and is already end of life. The last still supported were launched in 2010 [[1]](https://ark.intel.com/fr/search/advanced?s=t&FamilyText=Intel%C2%AE%20Atom%E2%84%A2%20Processor&InstructionSet=32-bit). All new intel processors (Joule/Curie etc) are 64-bit architectures.

Regarding statistics, Debian saw amd64 taking over i386 around mid 2012 and today there is a 3.6:1 ratio [[2]](http://popcon.debian.org/). For ROS packages, amd64 downloads exceeded i386 since 2015, last month's statistics of xenial downloads show amd64 packages downloaded ~20% more than i386 [[3]](https://awstats.osuosl.org/reports/packages.ros.org/2016/12/awstats.packages.ros.org.urldetail.html). We do suspect that most i386 downloads are made for computers supporting 64-bit instruction set but running x86 OSs

It would be interesting to see how many people among the community are actually installing ROS on 32-bit processors to make an educated decision.
