The original criticisms of the Adcorp Employment Index (February 2012)
Adcorp’s estimated unemployment rate is so low that it disposes of the unemployment crisis. But Adcorp uses a crude currency-demand method to estimate the size of the unrecorded economy, despite researchers’ strong criticism of this method. To estimate informal sector employment, Adcorp mixes up definitions of informal employment and the unrecorded economy and guesses at the labour intensity of the unrecorded economy. They also guess at the number of illegal immigrants. Moreover, Adcorp’s estimates have no statistical precision. Its figures are neither reliable nor credible.
Adcorp’s employment and unemployment figures are not taken seriously by researchers – yet they can do much harm
Adcorp’s unemployment figures are derived from weak research and is repeated too often by gullible journalists. Based on a flawed methodology and dubious assumptions, the Adcorp figures imply that only about a million people are unemployed and that the total unemployment rate is 5%. At the same time, Adcorp has published an inflated figure for graduate unemployment (600 000) – a grave inconsistency. Whilst serious researchers will not touch Adcorp data, it can harm decision-making by policymakers and potential university students and their parents.
