Interesting...probably because I join the next demographic soon :-)

1. Infancy: Birth-18 Months Old

During the first or second year of life, the major emphasis is on the mother and father’s nurturing ability and care for a child, especially in terms of visual contact and touch. The child will develop optimism, trust, confidence, and security if properly cared for and handled. If a child does not experience trust, he or she may develop insecurity, worthlessness, and general mistrust to the world.

2. Toddler / Early Childhood Years: 18 Months to 3 Years

The second stage occurs between 18 months and 3 years. At this point, the child has an opportunity to build self-esteem and autonomy as he or she learns new skills and right from wrong. The well-cared for child is sure of himself, carrying himself or herself with pride rather than shame. During this time of the “terrible twos”, defiance, temper tantrums, and stubbornness can also appear. Children tend to be vulnerable during this stage, sometimes feeling shame and and low self-esteem during an inability to learn certain skills.

3. Preschooler: 3 to 5 Years Izzy

During this period we experience a desire to copy the adults around us and take initiative in creating play situations. We make up stories with Barbie’s and Ken’s, toy phones and miniature cars, playing out roles in a trial universe, experimenting with the blueprint for what we believe it means to be an adult. We also begin to use that wonderful word for exploring the world—”WHY?”

The most significant relationship is with the basic family.

4. School Age Child: 6 to 12 Years Alex

During this stage, often called the Latency, we are capable of learning, creating and accomplishing numerous new skills and knowledge, thus developing a sense of industry. This is also a very social stage of development and if we experience unresolved feelings of inadequacy and inferiority among our peers, we can have serious problems in terms of competence and self-esteem.

As the world expands a bit, our most significant relationship is with the school and neighborhood. Parents are no longer the complete authorities they once were, although they are still important.

5. Adolescent: 12 to 18 Years

Up until this fifth stage, development depends on what is done to a person. At this point, development now depends primarily upon what a person does. An adolescent must struggle to discover and find his or her own identity, while negotiating and struggling with social interactions and “fitting in”, and developing a sense of morality and right from wrong.

Some attempt to delay entrance to adulthood and withdraw from responsibilities (moratorium). Those unsuccessful with this stage tend to experience role confusion and upheaval. Adolescents begin to develop a strong affiliation and devotion to ideals, causes, and friends.

6. Young adult: 18 to 35 Rob

At the young adult stage, people tend to seek companions hip and love. Some also begin to “settle down” and start families, although seems to have been pushed back farther in recent years.

Young adults seek deep intimacy and satisfying relationships, but if unsuccessful, isolation may occur. Significant relationships at this stage are with marital partners and friends.

7. Middle-aged Adult: 35 to 55 or 65 Me...soon!

Career and work are the most important things at this stage, along with family. Middle adulthood is also the time when people can take on greater responsibilities and control.

Major life shifts can occur during this stage. For example, children leave the household, careers can change, and so on. Some may struggle with finding purpose. Significant relationships are those within the family, workplace, local church and other communities.

8. Late Adult: 55 or 65 to Death

Erik Erikson believed that much of life is preparing for the middle adulthood stage and the last stage involves much reflection. As older adults, some can look back with a feeling of integrity — that is, contentment and fulfillment, having led a meaningful life and valuable contribution to society. Others may have a sense of despair during this stage, reflecting upon their experiences and failures. They may fear death as they struggle to find a purpose to their lives, wondering “What was the point of life? Was it worth it?”

We are about to take up 4 of these demographics soon. Strange to be completely out of the baby stage and I don't *feel* old enough to be middle age yet. Time is such a funny thing. You can never really imagine being a certain age and then one day, there you are!
