BLS publishes a comprehensive amount of data here: https://www.bls.gov/cpi/tables/supplemental-files/home.htm
However, this is probably the best view: https://data.bls.gov/timeseries/CUUR0000SA0?years_option=all_years
(There is a link to an XLSX file there. The link has no simple URL, since it allows many configuration changes)
Also, seems like FRED API may make some CPI data available to developers: https://fred.stlouisfed.org/docs/api/fred/ (includes a tool that runs in GoogleSheets)
- Vanguard/VT/USEquitiesPercentage
- metrics around market weights in my spreadsheet (how much SP500 vs Extended Market to get total stock, US vs Ex-US to get total world)
They later pointed to: https://www.bogleheads.org/wiki/Approximating_total_stock_market
Which appears to be an occasionally updated list...the core "morningstar style box" comes from https://www.morningstar.com/funds/xnas/vtsax/portfolio (choose stock style: weight)
Looking at Morningstar's APIs, you could automate grabbing the style box info from their securities API using equityStyleBox
and related data points.
Users pay $20 per month to get morningstar membership. So it likely isn't ok to store and share that data. Probably not something for financial-figures github and related sites to do without permissions from morningstar.
