Which of the following would be considered internal data for planning purposes?

Internal data refers to information that originates from within the organization and is used to aid in its planning and decision-making processes. The prior year's budget is a prime example of internal data because it reflects the organization's past financial planning and performance, providing a concrete benchmark for future budgetary considerations.

This data provides insights into previous spending patterns, resource allocation, and financial goals, allowing organizations to make informed adjustments for upcoming budgets. By analyzing their own historical budget data, businesses can identify trends, allocate resources more effectively, and set realistic financial objectives.

In contrast, local demographics, industry averages, and competitor profiles are classified as external data, as they involve information sourced from outside the organization that may influence planning but do not come from internal records.
