In 2010, the National Institute of Statistics replaced the National Employment Survey (ENE) with the New National Employment Survey (NENE) to align Chile with OECD best practices in the measurement of employment, unemployment and inactivity. This change may have unintentionally upward biased employment figures. The old survey recorded as employed only those people who spent most of the week working, whereas the new survey does it for everybody earning a salary for at least one hour per week.
