Construction Activity:

If a firm markets brick, lumber, gypsum products, builder's hardware and other building materials, its market depends on construction activity. Consideration is based on the number of value of building permits issued by a local authority.

Another way is to consider the number of construction work started and the type of structures, eg. single houses for residence, commercial houses, flats (apartment) and maisonettes. Local data are available from the local government offices.

Agricultural Activity:

The buying power of the farm market can be estimated by studying such indicators as cash from farm income, acreage planted and crop yields. If a firm markets agricultural products or equipment, the above estimates are essential for its effective marketing. For example, if you are a chemical producer selling to a fertilizer manufacturer, you need to study the same indices. Why? Because the demand for chemicals is derived from the demand for fertilizer.
