About these figures

  • These ABS figures count actively trading businesses, not workers, sites or venues, each in its main state or territory.
  • Entries and exits compare two 30 June counts. They are not counts of openings and closures.
  • The ABS adjusts its counts slightly to protect confidentiality, so a small number or a zero is approximate, not proof that no such business exists.
