S&P 500 Visualization Maps 412 Firms by Market Cap and Employee Density

The project renders each qualifying S&P 500 company as a circle whose area equals reported market cap, then populates the interior with identical stick figures whose count matches the headcount disclosed in the most recent annual report. Companies with fewer than 1,000 employees appear only when market cap exceeds the threshold, shown as half-size figures for Palantir and Welltower. Zoom and click functions expose exact ratios of market cap per employee and sector groupings.

Employee counts lag by up to twelve months and exclude contractors, producing systematic undercounting in software and semiconductor firms that rely on external labor. Market-cap figures update in real time while headcount remains static until the next 10-K, creating visible divergence for high-growth names whose valuations rose sharply after their last filing. This mismatch directly quantifies the gap between reported labor input and current equity value.

The visualization isolates asset-light models: Nvidia and similar firms display sparse figures inside large bubbles, while retailers and banks show dense packing. The pattern aligns with documented shifts in intangible-asset valuation recorded in Federal Reserve Z.1 tables and Compustat productivity series. Future releases will require quarterly headcount updates from 8-K or proxy statements to reduce the twelve-month lag and allow direct comparison against BLS employment statistics.
