An economist is a professional and practitioner in the social science discipline of economics.
The individual may also study, develop, and apply theories and concepts from economics and write about economic policy. Within this field there are many sub-fields, ranging from the broad philosophical theories to the focused study of minutiae within specific markets, macroeconomic analysis, microeconomic analysis or financial statement analysis, involving analytical methods and tools such as econometrics, statistics, economics computational models, financial economics, mathematical finance and mathematical economics.
Economists work in many fields including academia, government and in the private sector, where they may also "study data and statistics in order to spot trends in economic activity, economic confidence levels, and consumer attitudes. They assess this information using advanced methods in statistical analysis, mathematics, computer programming [and] they make recommendations about ways to improve the efficiency of a system or take advantage of trends as they begin." In addition to government and academia, economists are also employed in banking, finance, accountancy, commerce, marketing, business administration, lobbying and non- or not-for profit organizations.
In many organizations, an "Economic Analyst" is a formalized role.  Professionals here are employed (or engaged as consultants) to conduct research, prepare reports, or formulate plans and strategies to address economic problems. Here, as outlined, the analyst provides forecasts, analysis and advice, based upon observed trends and economic principles; this entails also collecting and processing economic and statistical data using econometric methods and statistical techniques.
In contrast to regulated professions such as engineering, law or medicine, there is not a legally required educational requirement or license for economists. In academia, most economists have a Ph.D. degree in Economics. In the U.S. Government, on the other hand, a person can be hired as an economist provided that they have a degree that included or was supplemented by 21 semester hours in economics and three hours in statistics, accounting, or calculus. In fact, a professional working inside of one of many fields of economics or having an academic degree in this subject is often considered to be an economist;  see Bachelor of Economics and Master of Economics.
Economics graduates are employable in varying degrees depending on the regional economic scenario and labour market conditions at the time for a given country. Apart from the specific understanding of the subject, employers value the skills of numeracy and analysis, the ability to communicate and the capacity to grasp broad issues which the graduates acquire at the university or college. Whilst only a few[quantify] economics graduates may be expected to become professional economists, many find it a base for entry into a career in finance – including accounting, insurance, tax and banking, or management; see financial analyst. A number of economics graduates from around the world have been successful in obtaining employment in a variety of major national and international firms in the financial and commercial sectors, and in manufacturing, retailing and IT, as well as in the public sector – for example, in the health and education sectors, or in government and politics. Small numbers[quantify] go on to undertake postgraduate studies, either in economics, research, teacher training or further qualifications in specialist areas.
In Brazil, unlike most countries in the world where the profession is not regulated, the profession of Economist is regulated by Law. 1411 of August 13, 1951. The professional designation of economist, according to the said law, is exclusive to the bachelors in economics graduates in Brazil.
According to the United States Department of Labor, there were about 15,000 non-academic economists in the United States in 2008, with a median salary of roughly $83,000, and the top ten percent earning more than $147,040 annually. Nearly 135 colleges and universities[verification needed] grant around 900 new Ph.D.s every year. Incomes are highest for those in the private sector, followed by the federal government, with academia paying the lowest incomes. As of January 2013, PayScale.com showed Ph.D. economists' salary ranges as follows: all Ph.D. economists, $61,000 to $160,000; Ph.D. corporate economists, $71,000 to $207,000; economics full professors, $89,000 to $137,000; economics associate professors, $59,000 to $156,000, and economics assistant professors, $72,000 to $100,000.
The largest single professional grouping of economists in the UK are the more than 3500 members of the Government Economic Service.
Analysis of destination surveys for economics graduates from a number of selected top schools of economics in the United Kingdom (ranging from Newcastle University to the London School of Economics), shows nearly 80 percent in employment six months after graduation – with a wide range of roles and employers, including regional, national and international organisations, across many sectors. This figure compares very favourably with the national picture, with 64 percent of economics graduates in employment.
Some current well-known economists include:
