"Measuring illegal economic activities is difficult, but information and guidance are available. Information may be obtained from administrative and law enforcement records, estimates of key inputs or major uses, and special research. Statistical institutions and data users have increasingly recognised the need for comprehensive, reliable and internationally available information on illegal economic activities in national accounts and balance of payments statistics. To this end, this Handbook provides guidance on:

  • the concepts and definitions of illegal economic activities;
  • recommended methodological frameworks for compiling data; and
  • data sources and statistical techniques for recording illegal economic activities."
