The classification scheme for the rating uses six levels for classification: large central metropolitan, large fringe metropolitan, medium metropolitan, small metropolitan, micropolitan and non-core.
The first group consisted of persons with residences in areas described as large central metropolitan, large fringe metropolitan and medium metropolitan; the other included persons living in areas described as small metropolitan, micropolitan, or non-core.
This study examines the extent to which local citizens prefer various development patterns for a roadway corridor at the fringe of a medium-sized community.
Summer O3 had a slightly stronger effect on reporting of respiratory allergy/hay fever in the more urban areas compared with the small metropolitan and rural areas, whereas PM10 and PM2.5 10 had slightly stronger associations in medium and fringe metropolitan areas (data not shown).
In the 1990s the focal points for migration were medium-sized cities (with 10,000 to 50,000 inhabitants), regions with strong service sectors, and the fringes of large and medium metropolitan areas.
In coarse-grained mediums the fringe may be flat at the top and thin, whereas in finer grained material it will tend to be higher and may be very irregular along the upper surface.
It forms ectomycorrhizae that have been called "Medium-Distance fringe exploration type", indicative of the ectomycorrhiza's ecological role in space occupation in the soil, their possible reach regarding nutrient acquisition and their demand of carbohydrates that have to be invested by the trees for their fungal partners.
For medium-sized fringe, use 3/4 inch (1.9 cm) slits.
To accommodate the relatively small number of outcome events, the scale was collapsed into three categories: large metropolitan (combining large central and large fringe metropolitan), medium/small metropolitan (combining medium and small metropolitan), and non-metropolitan (combining micropolitan and noncore), which was used as the primary independent variable.
