Tucked along Highway 80 in eastern Saskatchewan, Yarbo sits roughly 24 kilometres south of the Town of Churchbridge, placing it within the Rural Municipality of Langenburg No. 181 and Census Division No. 5. The community occupies a compact land area of 0.76 square kilometres, and as of the 2021 Census, 48 residents called it home, living in 25 of the 36 private dwellings available within its boundaries. That figure represented a decline of about 15.8 percent from the 57 residents recorded in the 2016 Census, which itself had reflected a modest increase from the 53 counted in 2011. The 2021 population density worked out to approximately 63.2 people per square kilometre.
Yarbo has a straightforward but notable administrative history. It was incorporated as a village on July 1, 1964, a status it held for six decades. On January 1, 2025, Yarbo dissolved its village status and transitioned into a special service area operating under the Rural Municipality of Langenburg No. 181, marking the end of its run as an independent incorporated community after more than 60 years.
