Development regions of Nepal
Prior to the promulgation of a new constitution in 2015 after an earthquake, Nepal was divided into five development regions (Nepali: विकास क्षेत्र), 14 administrative zones (Nepali: अञ्चल) and 75 districts (Nepali: जिल्ला). The 14 administrative zones were grouped into five development regions.
