4. Commercial Real Estate Industry
Revenue: $3,963 billion
The last five years have been a glorious one for this industry as it experienced an increase in global revenue. This industry unlike some of the others listed here depends entirely on global consumer spending, employment rates, per capita income, price of crude oil, etc. The United States, as well as some countries in Europe, have experienced stable and steady economic growth, driving the burgeoning middle class as well as the leading class to purchase real estate properties in and out of the country.
The case of UK citizens buying off homes in Turkey and in other parts of the world has greatly impacted the growth of this industry.
