# The analytical stack in 2001

Revision 1 (11 October 2026) · Modeled snapshot · through 8 October 2026.

All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

Integrated warehouse ownership persists

Tables follow the chart’s left-to-right order. Shares use each full layer as the denominator; subdivisions are included in their parent totals.
