The word "constable" generally indicates a lower-ranking officer, and in the case of detective work, a detective constable is an officer who has completed two years of training and has transferred into criminal investigation, according to the Norfolk Constabulary. As a detective constable rises through the ranks of detective sergeant and detective inspector, his salary rises as well.
The Bureau of Labor Statistics classifies detective constables along with detectives and criminal investigators, who earned an average salary of £47,456 as of May 2010. Because constable is one of the lowest-ranking positions of detectives, they tend to earn a lower salary on the scale. Wages were less than £25,252 for detectives in the 10th percentile and less than £32,513 in the 25th percentile annually.
The bureau reports that the government was the largest employer of detectives, including detective constables, as of 2010. Those working for local governments earned an average of £40,254 a year, those working for state governments earned an average of £35,321, and those working for the federal executive branch earned an average of £60,586. The postal service employed detectives and detective constables for an average salary of £59,000 a year, and colleges, universities and professional schools offered a salary average of £40,495.
The state of New Mexico had the highest concentration of detective positions, including that of detective constable, as of 2010, offering a salary average of £44,486 a year. The District of Columbia offered the highest salary average at £69,647 a year, according to the bureau, followed by New Jersey at £59,923. Northwestern Washington was the highest-paying rural area for this profession, with a salary average of £48,834 a year.
The bureau predicts an increase of 10 per cent in the employment of police and detectives between 2008 and 2018, which is attributed to population growth. A higher level of competition is expected for detective constables seeking work with federal and state law enforcement agencies, as these employers typically require prior investigative experience, while local government agencies offer more opportunities for constables and other entry-level detectives.
