However, as shown in figure 2.5, progress in access progressively decelerated after 2008, from 0.7 percentage points to 0.5 percentage points per year. Even discounting this slowdown, the overall rate of progress is not enough to reach SDG target 7.1 by 2030. Moreover, as seen in previous years, population growth continues to outpace access in Sub-Saharan Africa. Figure 2.6 compares the annual increase in the number of people with access to clean fuels and technologies (yellow) to the annual population increase (orange), by region, over the period 2015-2017. It can be seen that, over this period, population growth in Sub-Saharan Africa vastly outstripped growth in the number of people with access to clean cooking solutions. In 2017 around 3 billion people lacked access to clean fuels and technologies for cooking; in 2030 around 40% of the access-deficit population will reside in Sub-Saharan Africa and around 26% in Central and Southern Asia.
