Rates of depression increase during adolescence and may put youth at risk for suicidality, future episodes, and impaired functioning in multiple life domains. Increased vulnerability for depression during this stage may occur because it is when the cognitive capacity for personal reflection, abstract reasoning, and formal operational thought develop; depressive styles for attributing events may hence form, along with hopelessness about the future. However, other biological and social influences may also interact with the increased cognitive vulnerability. Latino ethnicity and female gender appear to exert particular influence. Treatment for adolescent depression includes medication (mainly Prozac and Zoloft), cognitive-behavioral therapy, interpersonal therapy, and family therapy. Medication and psychosocial treatment is also combined, particularly for treatment-resistant depression.

This entry provides a brief overview of the field of social demography, the components of population change, projections for future population growth, and recent transformations in population composition pertaining to age, race, and ethnicity. Trends that shape family household structure (for example, marriage, divorce, cohabitation, and nonmarital child bearing) are also considered, as are trends pertaining to the distribution of income, wealth, and poverty. Population trends given particular attention include the growth of class-based disparities in marriage and nonmarital child bearing, the contributions of immigration to population growth and diversity, and a disturbing increase over recent decades in the prevalence of poverty among children of immigrants.
