Methodology
For each asset class in 2024, divide current-cost depreciation and net investment (gross investment minus depreciation) by year-end current-cost net stock, then multiply by 100. The stacked components sum to gross investment per $100 of net stock. This is an accounting-flow decomposition, not a direct observation of replacement projects or asset age. Limitations: BEA's intellectual-property category covers software, R&D, and artistic originals—not brands, organizational capital, customer relationships, data, or every economically valuable intangible. Current-cost values combine quantity and price change; these charts do not measure real growth unless explicitly stated. BEA revises Fixed Assets history; the generator pins the workbook vintage and reruns component and period checks. Depreciation is a BEA estimate based on service lives and depreciation patterns, not observed physical failure or a direct measure of technological obsolescence. Using year-end net stock in the denominator slightly differs from an average-year capital base; the same convention is applied to all three assets.
