The percentage of employees with families varies widely from place to 

 place and from time to time. Among influential factors are: 



-- The character of the study region. A smaller percentage of 

 resident families is likely to be attracted to areas, such as 

 parts of Alaska, where living conditions are different from those 

 to which most American families are accustomed. 



-- The stage of facility development (construction or operation). A 

 higher percentage of single people is usually associated with 

 facility construction than with operation. Longer term positions 

 are more likely to attract a higher percentage of employees with 

 families. 



-- The type of facility. The employees who operate some types of OCS 

 facilities, notably exploratory rigs and pipelaying barges, 

 customarily migrate from job to job. If these employees have 

 families, they customarily leave them near a fixed home base.
