Projections in a recent OECD report indicate that high levels of informality will prevail well into the future, as a result, the growth in social insurance coverage evident in the recent past is unlikely to maintain this trajectory (OECD, 2017[2ij). Due to the timing of its launch, expenditure on CBHI is not covered in the expenditure analysis for the period 2012/13 to 2015/16. However, a rapid increase in enrolment suggests that spending on CBHI will grow strongly over in the near future.
