International Trade Data (HS, 92)

<p>
<a href="http://atlas.hks.harvard.edu">The Atlas of Economic Complexity</a> maintains trade data in multiple international classification systems. This data set contains trade flows classified via Harmonized System (HS) 1992. HS data offers a contemporary and detailed classification of goods, but covers a relatively short time period:
</p>

<ul>
<li>Categorizes approximately 5,000 goods</li>
<li>Coverages starts in 1995</li>
<li>Categories break down to 1-, 2-, 4-, or 6-digit detail levels (though country reporting can be less reliable at the 6-digit level)</li>
</ul>

<p>
Raw data on trade in goods is provided by <a href="https://comtrade.un.org/">United Nations Statistical Division (COMTRADE)</a>. The data is then cleaned by Growth Lab researchers using the Bustos-Yildirim Method which uses bilateral trade flows to account for inconsistent reporting and provides more reliable accounting.
