A quick skim suggests projections haven't changed much compared with the 2015 report.
- Linear growth +83m/yr
- 24 years for last +2b = +1 every 12 years
- Currently 7.55b
- 9.7b in 2050
- No peak this century
- Main growth from Africa / India / China.

The pages at http://www.worldometers.info/world-population/ haven't yet been updated to suit but the projections look broadly the same. eg 8b in 2023, 9b in 2038, 10b in 2056

There's the usual rider from this observer. This analysis is based on business as usual continuing as long as possible and certainly out to 2100. It doesn't take into account any Limits to Growth style instability or non-linearity.
