Since 1960, the Bank of Korea has published its annual Economic Statistics Yearbook containing Korea’s major economic statistics 
by sector. To help understand the economic trend up until recent years, this book consists of the following statistics produced by 
the Bank: the five major national accounts ? the national income, the balance of payments, the flow of funds, the input-output tables 
and the national balance sheet; monetary and financial statistics; price indexes; and financial statement analysis. The book also 
includes economic indicators of major countries.

   In this 2020 edition in particular, the reference year for the national balance sheet was revised from 2010 to 2015, and the tenth 
revision of the Korean Standard Industrial Classification was applied to financial statement analysis.

   In addition, efforts have been made to enhance user convenience by increasing and improving infographics, expanding and 
bolstering the national account-related items for principal economic indicators, and further clarifying footnotes to the statistics. 

   All information in this report is also available on the Bank of Korea’s website (https://www.bok.or.kr) and principal economic 
indicators are accessible through the mobile ECOS website (http://ecos.bok.or.kr/mobile).

   I sincerely hope that this publication will be found useful by the policy authorities and general users. I would like to ask our 
readers not to hesitate in giving us their candid feedback and advice on any content that requires further improvement. Lastly, 
I wish to express my deep appreciation to those who have generously helped with the publication of this report.
