Borough (Pennsylvania)
In the U.S. Commonwealth of Pennsylvania, a borough (sometimes spelled boro) is a self-governing municipal entity, equivalent to a town in most jurisdictions, usually smaller than a city, but with a similar population density in its residential areas. Sometimes thought of as "junior cities", boroughs generally have fewer powers and responsibilities than full-fledged cities.

The only exception is the town of Bloomsburg, recognized by the state government as the only incorporated town in Pennsylvania. Boroughs tend to have more developed business districts and concentrations of public and commercial office buildings, including court houses.

In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity.

Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses.

UN recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practices. The UN's Food and Agriculture Organization (FAO), in turn, defines the census of agriculture as "a statistical operation for collecting, processing and disseminating data on the structure of agriculture, covering th ...

Coal Mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily to th ...
