Measuring homelessness is difficult because of the fluidity of the homeless population. Part of the difficulty stems from varying methodologies used to measure homelessness. Some researchers attempt to count all the people who are literally homeless on a given day or during a given week, called a point-in-time count. Critics say this method is likely to overestimate the number of chronically homeless and underestimate the number of people who experience temporary homelessness.
What is an 'Auditor'. An auditor is an official whose job it is to carefully check the accuracy of business records. An auditor might be either an internal auditor, external auditor or independent auditor for accounting firms in the public or private sector. Auditors can also work for many different entities, such as the IRS or a state government.
Auditors assess the risk of material misstatement in a company's financial reports. Without a system of internal controls or an audit system, a company would not be able to create reliable financial reports for internal or external purposes.
