Price index illustrating the relative change relative to last year's price for the COVID-19 period in Kano and Katsina, based on FPCA 2019-20 data in Nigeria, contrasted with the price data reported by the National Bureau of Statistics (NBS) of Nigeria. For comparison, the light grey line (NBS, 2017-19) illustrates the average price index of change for the past two years (i.e. 2019 -2018 and 2018–2017), based on the NBS data. For the period 2019–20, the index for rice was relatively stable, however, it follows an upward trajectory for maize presumably due to government's restriction of maize importation which resulted in steep increase of maize prices.
