In addition to reporting on the number of people benefiting, also provide qualitative information on how they benefit.
This indicator gives only a rough estimate of how many people have benefited. Such estimates are often too optimistic. If you need to have more reliable evidence, you could conduct a survey among a representative sample of the people who were supposed to benefit and measure how many have gained the desired benefits. However, in most circumstances, this is not necessary for Tearfund’s purposes.
Any proper advocacy strategy should already include an initial assessment of how many people are impacted by a given issue, which can help you estimate the benefits brought by successful advocacy efforts to secure a particular policy or practice change.
