"The results showed that counties with large commercial centres such as Nairobi City, Kiambu, Mombasa City, Nakuru City and Machakos, had relatively high Gross County Product (GCP) compared to counties with predominantly rural settings.
"Nevertheless, counties with a wide range of economic activities, especially agricultural production such as Meru, Kakamega and Nyeri also accounted for notable proportions of GCP to total GVA," read the report in part.
