Several data files are attached. Each data file contains the market value by country of 
US holdings of long-term securities that are considered foreign on a residence basis 
as published in the Treasury International Capital data, and their corresponding values 
on a nationality basis, for end-December of each year.  
Data are now extened to cover 2003-2020; estimates for prior years may be revised. 
The "mv_difference_nat_vs_res_YYYY" columns show the difference
in market value for each country on a nationality versus residence basis.

Data are broken into separate data files by asset type. The following data files are included:

total_equity_and_bonds_data_table.csv: Holdings of all equity and bonds

total_equity_data_table.csv: Holdings of all equity (common stock, fund shares, and preferred and other equity). 
    
common_stock_data_table.csv: Holdings of common stock

fund_shares_data_table.csv: Holdings of fund shares. Note that official 
    statistics consider all fund shares to be “equity” regardless of 
    the investment focus of the fund.

preferred_and_other_equity_data_table.csv: Holdings of preferred equity and 
    "other equity", which are equity holdings other than common stock,
    preferred stock, and fund shares.

total_bonds_data_table.csv: Holdings of both government and corporate bonds.

gov_bonds_data_table.csv:  Holdings of government bonds.

corporate_bonds_data_table.csv: Holdings of corporate bonds

Authors' estimates are based on Treasury International Capital data.
