Deputy Government statistician, Baah Wadieh, attributed the marginal increase in the index was mainly to a rise in transport fares which went up by 9.6 percent last month.
He said that the monthly change rate in April 2017 was 1.6 per cent, while that for March 2017 stood at 1.3 per cent.
The year-on-year non-food inflation rate recorded for April was 16.3 per cent compared with the 15.6 per cent recorded in March 2017.
The non-food inflation rate was more than two times that of the food inflation rate of 6.7 per cent compared with 7.3 per cent recorded in March 2017.
The main “price drivers” for the non-food inflation rate were transport 24.9 per cent, recreation and culture 22.3 per cent, furnishings, household equipment and routine maintenance 21.9 per cent, miscellaneous goods and services 16.8 per cent and clothing and footwear 16.7 per cent.
The “price drivers” for the food inflation rate were fish and sea food 13.6 per cent, meat and products 10.9 per cent and coffee, tea and cocoa 7.2 per cent.
In April 2017, the year-on-year inflation rate for imported items which stood at 15.0 per cent was 2.8 percentage points higher than the locally produced items of 12.2 per cent.
Four regions, the Greater Accra, Upper West, Brong Ahafo and Ashanti recorded inflation rates higher than the national average and Western region recorded the same inflation rate as the national average.
The Greater Accra region recorded the highest year on-year inflation rate of 14.2 per cent, followed by the Upper West region with 13.7 while the Volta region recorded the lowest.
Ghana, which exports cocoa, gold and oil, said in April it was committed to reducing inflation, public debt and the budget deficit. It was one of Africa's best-performing economies until 2014, when it was hit by a slump in commodity prices.
