How Can I Find Information in AgeLine
on Specific Age Groups or Cohorts?


The AgeLine database has been specially designed to help you find information on specific age groups and cohorts. The information below identifies the age group Subjects (also known as Keywords or Descriptors) and cohort Subjects you would find if you used the AgeLine Thesaurus of Aging Terminology or browsed the Subject Index on the Advanced Subject Search or Multiple-Options Search screens to create your search queries.

To search using these age group and cohort Subjects, use the Advanced Subject Search or the Multiple-Option Search screens.

Age Groups


AgeLine abstracts always include age information about the individuals or groups of people who are the focus of the document or research study when that information is available in the document. In a research study, this information typically includes the age range and mean age. When indexing an AgeLine abstract, AgeLine editors use two types of age group Subjects: one type indicates the youngest age of the population covered in the study or discussion, and the other indicates the age range of the study population. These age group Subjects can help users narrow their searches to books and articles focusing on particular age groups.

    18+   60+
    25+   65+
    30+   70+
    35+   75+
    40+   80+
    45+   85+
    50+   90+
    55+   95+
        Centenarians

For example, if the population in a study is described as being aged 65 and older, the Descriptor 65+ is added as a Subject to the AgeLine record describing that study.

        Subjects                     Approximate Age
Range

       Preschool Age Children       2-5
        Children       0-12
        Adolescents       13-17
        Young Adults       18-24
        Adults       25-39
        Middle Aged       40-59
        Young Old       60-74
        Old Old       75-100+
        Older Adults       60+
        Centenarians       100 years and older
        Under 65       64 years and younger
        Adults of All Ages       18 years and older

For example, if a study population is described as being aged 65-74, the Subjects 65+ and Young Old are both used. If this population is also compared with a middle-aged population ranging from 42-55 years of age, the Subjects 40+, Middle Aged, and Age Differences also apply.

Examples
If you are interested in finding research on depression in middle-aged adults, try the following while on the Advanced Subject Search screen:
middle aged
AND
depression
In the Limit Results area of the screen, next to Audience Type(s), select
Research.

If you are looking for comparisons between the old-old and young-old populations, try the following on the Advanced Subject Search screen:

AND
young old
AND
age differences
If you would like to find descriptions of intergenerational programs involving preschool age children and older adults, try the following on the Advanced Subject Search screen:
preschool age children
AND

Note: There is no need to add the Subject Older Adults, since almost all of the AgeLine database covers the older population.
If you would like to find studies that survey adults of all ages and focus on retirement planning, try the following in the Advanced Subject Search screen:
18+; adults of all ages
AND
surveys
AND

If you would like to find research on differences between those 65 and older and those under 65, try the following in the Advanced Subject Search screen:
65+
AND
Under 65
AND
Age Differences
In the Limit Results area of the screen, next to Audience Type(s), select

If you would like to locate profiles of individuals aged 90 and older, try the following in the Advanced Subject Search screen:

Cohorts

AgeLine also indexes for the following generational cohorts:

Baby Boom Generation Population cohort born between 1946
and 1964 in the United States.
Baby Bust Generation Individuals born between 1965 and 1976
in the United States, who form a smaller
cohort than the baby boom generation.
Echo Boom Generation Children of baby boomers born between
1977 and 1993.
Sandwich Generation Adults who have caregiving
responsibilities for their dependent
children and their aging parents.

Consider searching the Subject Intergenerational Differences if looking to identify studies comparing cohorts.
