The Terror of Sally Sparrow is a gargantuan, environmentally stunning nation, notable for its absence of drug laws and spontaneously combusting cars. The hard-nosed, hard-working, democratic population of 22.825 billion Sparrows live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The medium-sized, liberal, pro-business, outspoken government juggles the competing demands of Education, Welfare, and Environment. Citizens pay a flat income tax of 25.9%.

The strong Sally Sparrow economy, worth 943 trillion Pounds a year, is quite specialized and led by the Trout Farming industry, with major contributions from Basket Weaving, Pizza Delivery, and Woodchip Exports. Average income is 41,326 Pounds, but there is a vast disparity between incomes, with the richest 10% of citizens earning 280,967 per year while the poor average 2,220, a ratio of 126 to 1.

Crime is a serious problem. Sally Sparrow's national animal is the Angel, which frolics freely in the nation's many lush forests.

Sally Sparrow is ranked 79,256^th in the world and 7^th in The Doctor Who Universe for Most Beautiful Environments, with 596.83 pounds of wildlife per square mile.
