The bar chart compares the export values, measured in billion dollars, of five commodity categories of a country between 2015 and 2016, while the table shows their growth rates in that period.

Overall, export earnings from all product categories increased, with the exception of gems and jewellery. In addition, although textiles contributed the least among those types of commodity, it had the largest growth rate.

Earnings from the export of petroleum products was highest in both years: it was just over 60 billion dollars in 2015 and then increased by 3% to about 62 billion dollars in 2016. Engineered goods contributed about 57 billion dollars in 2015 and roughly 61 billion dollars in the following year (rising by 8.5%).

The only negative growth rate (-5.18%) belonged to gems and jewellery’s export value, which stood at about 42 billion dollars in 2015 then declined to just over 40 billion dollars. Earnings from textiles was roughly 26 billion dollars in 2015 but grew significantly by 15.24% to about 31 billion dollars, which was almost equal to that of agricultural products in both years.
