A general / simple definition of economics is the production, distribution, and consumption of goods and services. An economics major, will more than likely engage in learning activities that will enable you develop valuable skills including how to analyze complex sets of data, observe and evaluate patterns and trends; extrapolate meaning from data sets, observations and various sources of information, understanding how and why things may or may not work. You are also more than likely to be exposed to tools, software and systems that support research, analysis, decision making, documentation, planning, presentation. And you will have opportunities to develop your writing, speaking, presentation and teamwork skills.
In my opinion these skills are not only foundational and critical for an economics major but they are applicable, transferable, valuable and indispensable skills for all professions and life in general. At the core, economics helps develop understanding and appreciation of relationships and connections, as well as knowledge of how to support the connections with available resources.
I have an undergraduate degree in Economics which served as a well-rounded degree because at the time I wanted to and have had the opportunity to explore / work in different industries (wealth / investment management, marketing and communications, project finance). I eventually decided to focus on a career in risk management and have since earned graduate degrees in business and financial management. Here again, even after several years, my undergraduate degree in economics provided the perfect launch pad.
Best wishes to you!
