  • US Household Financial Pressure (derived)

    US household financial pressure, monthly

    Monthly US household financial-pressure panel, 2005-01 through 2026-07, built from three public-domain US federal series (the FRED series TDSP/PSAVERT/DSPIC96, retrieved from the original releases): the household debt-service ratio (percent of disposable personal income, quarterly, carried as-of to months), the personal saving rate PSAVERT (percent, SAAR), and real disposable personal income DSPIC96 (billions of chained 2017 dollars, SAAR). Ships ML-ready derived features: discretionary_income_proxy_bn (real DPI after required debt-service payments), financial_pressure_index (trailing-10-year z-score composite of debt burden vs saving rate; positive = tighter than the last decade), and 12-month changes. Base values transcribed verbatim from the official source releases (2026-09-28); derived columns are this connector's transformation.

  • North America retail events calendar

    North America retail events calendar, yearly

    Yearly calendar of North American retail events (Black Friday, Cyber Monday, Boxing Day, Amazon Prime Day, back-to-school Labour Day anchor, US and Canadian Thanksgiving), 2015 to the present, for US and Canada. Each event row carries ML-ready countdown features: days to Christmas, days remaining in the year, and a holiday-season (Nov/Dec) flag. Holiday rules: US Thanksgiving = 4th Thursday of November (federal since 1941); Canadian Thanksgiving = 2nd Monday of October (1957 proclamation); Boxing Day = Dec 26; Prime Day dates curated from Amazon's announcements (multi-day spans recorded as event_date..event_end_date). No future-year rows: Prime Day dates are announced annually and added on the yearly refresh.

  • TSA checkpoint travel volumes

    TSA checkpoint travel volumes, daily

    Daily US airport checkpoint throughput (travelers screened), 2019-01-01 to the latest TSA publication, from the TSA's official passenger-volumes pages. Derived ML features: trailing 7-day average (passengers_7d_avg), year-over-year % change (yoy_change_pct), 2019-baseline recovery ratio (recovery_ratio_2019; 2019 is the pre-pandemic reference), day-of-week seasonal ratio (dow_seasonal_ratio, look-ahead-free), and a trailing-365-day record-high flag (record_high_365d). Nulls are honest (insufficient history), never interpolated.
