Last 90 days beside the year before

Two counts, never a ratio: filings dated in the last 90 days, and the 365 days before that scaled to the same length. USAspending publishes Defense contract data 90 days late, so for an entity with Defense work the window is missing awards the baseline year is not; the watchlist explains how to read the pair.

By year

Every filing on record for this entity, counted by the year of its own date: the Base Obligation Date for a contract award, the date the Senate posted it for a lobbying filing. A contract total is the sum of those awards’ current totals, so an award first obligated in an earlier year carries its later modifications with it.

The store’s record does not reach equally far back on both sides. It holds no lobbying filing for any entity before 2024, so lobbying for earlier years is marked not in the record rather than counted as zero. A contract award obligated before November 2024 is on record because the historical sweep, which looked back to 1 November 2024 by action date, found a later action on it, so an earlier year counts the awards still active since then, not everything obligated that year.

Agencies, 2026

This year’s lobbying filings by the agency they name, beside this year’s new contract awards by the agency that made them. The entity level version of the by agency table on the confluence page, for the calendar year rather than the 90 day window, and with agencies named only in lobbying listed too. 25 lobbying filings this year; one that names several agencies counts on each of their rows, so the lobbying column does not sum to that figure. Lobbying is matched to agencies through the hand kept agency crosswalk.
