In 2016, Nigeria comparatively ranked better when it scored 28 and took 136th position among the 176 countries evaluated for that year; meaning that Nigeria was in 2016 better than 40 other nations. The one-point reduction in Nigeria's score slipped the country down by 12 positions; from 136th in 2016 to 148th in 2017.
CPI ranking relates to perceptions of the degree of corruption as experienced by business people and analysts; using a scale that ranges between 0 (highly corrupt) and 100 (very clean). CPI is one of the most respected international measurements for corruption trends across all continents. It was established in 1995 as a composite indicator used for measuring perceptions of corruption in the public sector in different countries around the world. CPI is computed by the TI Secretariat in Germany and is published in Nigeria by the Civil Society Legislative Advocacy Centre (CISLAC).
