Each arrival is counted separately and includes people traveling more than once a year and people visiting several cities during one trip. The growth column compares international arrivals to the previous year.

An asset management company is an asset management / investment management company/firm that invests the pooled funds of retail investors in securities in line with the stated investment objectives. For a fee, the company/firm provides more diversification, liquidity, and professional management consulting service than is normally available to individual investors. The diversification of portfolio is done by investing in such securities which are inversely correlated to each other. Money is collected from investors by way of floating various collective investment schemes, e.g. mutual fund schemes. In general, an asset management company is a company that is engaged primarily in the business of investing in, and managing, portfolios of securities. A study by consulting firm Casey Quirk, which is owned by Deloitte, found that asset management firms ended 2020 with record highs in both revenue and assets under management.

Management science (or managerial science) is a wide and interdisciplinary study of solving complex problems and making strategic decisions as it pertains to institutions, corporations, governments and other types of organizational entities. It is closely related to management, economics, business, engineering, management consulting, and other fields. It uses various scientific research-based principles, strategies, and analytical methods including mathematical modeling, statistics and numerical algorithms and aims to improve an organization's ability to enact rational and accurate management decisions by arriving at optimal or near optimal solutions to complex decision problems.

Management science looks to help businesses achieve goals using a number of scientific methods. The field was initially an outgrowth of applied mathematics, where early challenges were problems relating to the optimization of systems which could be modeled linearly, i.e., determining the optima (maximum value of profit, assembly line performance, crop yield, bandwidth, etc. or minimum of loss, risk, costs, etc.) of some objective function. Today, the discipline of management science may encompass a diverse range of managerial and organizational activity as it regards to a problem which is structured in mathematical or other quantitative form in order to derive managerially relevant insights and solutions.

The Big Four are the four largest professional services networks in the world: Deloitte, EY, KPMG, and PwC. They are the four largest global accounting networks as measured by revenue. The four are often grouped because they are comparable in size relative to the rest of the market, both in terms of revenue and workforce; they are considered equal in their ability to provide a wide scope of professional services to their clients; and, among those looking to start a career in professional services, particularly accounting, they are considered equally attractive networks to work in, because of the frequency with which these firms engage with Fortune 500 companies.

The Big Four all offer audit, assurance, taxation, management consulting, valuation, market research, actuarial, corporate finance, and legal services to their clients. A significant majority of the audits of public companies, as well as many audits of private companies, are conducted by these four networks. Until the late 20th century, the market for professional services was dominated by eight networks which were nicknamed the "Big Eight". The Big Eight consisted of Arthur Andersen, Arthur Young, Coopers & Lybrand, Deloitte Haskins and Sells, Ernst & Whinney, Peat Marwick Mitchell, Price Waterhouse, and Touche Ross.

Frederick Winslow Taylor (March 20, 1856 – March 21, 1915) was an American mechanical engineer. He was widely known for his methods to improve industrial efficiency. He was one of the first management consultants. In 1909, Taylor summed up his efficiency techniques in his book The Principles of Scientific Management which, in 2001, Fellows of the Academy of Management voted the most influential management book of the twentieth century. His pioneering work in applying engineering principles to the work done on the factory floor was instrumental in the creation and development of the branch of engineering that is now known as industrial engineering. Taylor made his name, and was most proud of his work, in scientific management; as a result, scientific management is sometimes referred to as Taylorism. However, he made his fortune patenting steel-process improvements.

He was one of the founders of the Jobs to Be Done development methodology.
