Annual transition rates are calculated over the following periods for China (2008-09), Colombia (2009-10) and Tbrkey (2010-11), while the figures for South Africa represent bi-annual transitions calculated over the 2010-12 period. This is particularly striking in South Africa, where the economic crisis led to a dramatic flow into inactivity, which was particularly significant among informal workers. Overall, it appears that informal jobs are highly volatile. The results are summarised in Annex Figure 5.A3.1.
