Additional users measure how many more women are using modern contraception in the current year, as compared to the number who were using in 2012. Additional users is an aggregate concept measuring change at a population level.
The number of additional users of modern contraceptive methods is FP2020’s Core Indicator 1, and measures progress towards the initiative’s goal. Reaching additional users means countries are both sustaining services to women who were already using modern contraceptives in 2012, and, this, increasing the number of users further.
The headline goal for the FP2020 initiative is increasing the number of women using a modern contraceptive method by 120 million between 2012 and 2020.
Additional users are calculated from a total increase in the number of modern contraceptive users in a country. This increase in additional users is not the same as measuring increases in modern contraceptive prevalence (mCPR). This is because in countries where the number of women of reproductive age (15-49) is growing year after year, there will need to be growth in users to just maintain the baseline mCPR.
Once this is done, additional gains in users are made by expanding family planning programs to further increase the mCPR. Additional users capture both concepts. This means that in countries with increasing numbers of women of reproductive age, their additional user numbers will increase each year, even if mCPR remains constant.
The graph shows an example of this concept for Bangladesh and Ethiopia. Both countries had a similar number of additional users in 2017. However, in Bangladesh the majority of additional users came from maintaining the 2012 mCPR (e.g. accounting for an increased number of women of reproductive age) while in Ethiopia the majority of additional users were due to increases in mCPR.
Additional users are measured from the FP2020 “baseline” year of 2012. This means that there were zero additional users in 2012, and from 2013 onwards, additional users are reported as the difference between the total number of users in the current year, and the number of users there were in 2012. This allows for estimating the cumulative number of additional users through any given year in comparison with 2012.
The total users in each year are calculated by multiplying the mCPR in that year by the estimated number of women of reproductive age in the same year. For more about calculating mCPR, see the Technical Brief on FPET.
To illustrate, the estimated number of modern contraceptive users in Kenya in 2017 was 5.3 million. To calculate the number of additional users from the FP2020 baseline year of 2012 to the year 2017, the estimated number of contraceptive users in 2012 (3.7 million) is subtracted from the 2017 estimate, yielding a value of the indicator number of additional users in 2017 of 1.6 million (see green bar in graph to right).
The calculation of Indicator 1 “Additional Users of Modern Contraception” is based upon a “rolling baseline” for the year 2012. The rolling baseline takes into account the fact that past population size estimates and mCPR estimates will likely change as new census and survey data become available.
