• Many of the terms can be prefixed with the word private or the word professional. These are not shown here as alternatives.
• Investigators and Detectives are the most common terms. Investigations is the third most popular general term.
• Agent is a term that is used in conjunction with another word, such as Enquiry Agents and Solicitors Agents, as well as Detective Agent and Investigation Agent.
• Agency and Bureau are two terms used to describe a company providing investigation services. The terms may also be combined with other terms, such as Detective Agencies, Detective Bureau and Bureau of Investigation.
