Where can I find data on market capitalization? I am working on Home Equity/Bond Bias and need data to calculate the indicators of Home Equity Bias. So where can I find data on market capitalization (stocks and bonds) by year for each country?

Many thanks for your help.
Market capitalization of listed domestic companies (% of GDP) across years and countries from the World Development Indicators in the World Bank data website or the United Nations one.
FRED economic data on market capitalization.
Focusing on European Countries: the ECB website.
