Did You Know?
‣ What is the relationship between Black child poverty and Black child placement rates?
‣ What is the likelihood a child age 10 at the time of admission will age out of foster care?
2% or 4% or 15%‣ Match the age group to their proportion on the caseload
Infants (under 1) 4%
10 year olds 7%
Teens (14 - 15 yr. olds) 24%‣ Of foster parents who are licensed and eligible to accept to children into their home, what

Placement Disparity
‣ If versus who, where and when
University of ChicagoChapin Hall Center for Children
Center for State Child Welfare Data
Disparity in Tn.
‣ Are Black children are over represented in foster care?‣ 22% of all children are Black whereas 28% of foster children are Black
‣ How did/does this happen?
‣ Black child admission rate: 3.78 placements/1,000 Black children
‣ White child admission rate: 2.99 placements/1,000 White children
‣ Disparity ratio: 1.27
‣ Conclusion: Black children are 27 percent more likely to enter care than white children
‣ No difference in exit rates?
‣ Conclusion: Black children leave foster care as quickly as white children do?‣

Congregate Care and the Theory of Ecological Similarity
‣ Robert Sampson and others including William J. Wilson‣ Exposure to similar circumstances
‣ Congregate care‣ Is bed supply a factor in demand?
‣ Congregate care placements and Black/white disparities
‣ Does ecological similarity matter?
‣ Measure of supply induced demand‣ Do entry and exits move together over time?

Center for State Child Welfare Data
What Does All of This Mean?
‣ The starting point:
‣ Constraints on decisions affect what happens to children
‣ Beds are a constraint
‣ Systems where supply has a strong effect will increase the likelihood of entry into congregate care
‣ Age, prior history of placement in group care, and location are all important
‣ Has consequences for disparity

a denotes the age of the child at which measurement is conducted, l is an index that identifies whether the skill is cognitive (C) or non-cognitive (N) and k indicates the
type of risk or protective factors the child experienced at age a. For the sake of illustration, risk and protective factors can only occur at the parent (P), environment
(E) or School (S) level.

Human Capital as Wellbeing
‣ Human capital is the diverse bundle of skills that young people need to manage the next set of challenges life puts in front of them‣ The skills involved are diverse: soft skills, hard skills, ability, know-how,
education, and experience.
‣ The skills acquired are age-dependent and cumulative ‣ Time scale can be daily or across the life course - transitions are how
narrative coheres‣ In time, the bundle of skills is what differentiates adults and children.
‣ Adults possess the skills needed to manage relationships with other adults, relationships with the community, and a relationship with the workforce.
University of ChicagoChapin Hall Center for Children
Center for State Child Welfare Data
Foundational Ideas
‣ Formation of human capital starts early‣ The rudimentary skills of language, numeracy, motor skills, emotional regulation‣ The formation of human capital follows a trajectory
‣ Human capital begets human capital‣ The rate at which human capital forms is a function of the stock of human capital
plus risk and protective factors‣ Easier to make gains in kindergarten if you have a larger vocabulary, etc.
‣ By rebalancing risk and protective factors, the rate of human capital formation will accelerate
‣ Raise protective factors by addressing the micro-social interactions between adults and children and improving the institutional structures that bring children together with adults (i.e, day care, housing, etc.).

These are bi-directional processes. Our challenge is to identify the contextual elements most likely to manifest themselves as bio-psychological influences and vice versa.
What features of context - contextual determinants - influence development?
Whether they are human-built (health care/child welfare) or natural (families), systems are a key feature of context.

Time / Development
Human capital is a diverse bundle of assets - skills (cognitive, social emotional), experience, know-how, etc.
The stock of human capital changes over time. The rate of change - the trajectory - is relevant for policy and practice
Risk factors slow the rate at which human capital forms
Protective factors raise the rate at which human capital forms. The stock of human capital is a protective factor.

Human Capital is a function of:
The person period as a developmental construct - as young people grow older change occurs in accordance with developmental changes, caregiver skills, and the interaction between the two, etc.
Person-period characteristics measured as attributes of the family and the community. During the person-period, the absence or presence of these factors affects wellbeing depending the risk/protective nature of contextual influences that happen to be present.

These results show that children at home when the wave 1 interviews took place had good language skills. By wave 5 children at home fell behind. The same can be said for children who spent some time in foster care but where never adopted. Children who were adopted improved their language skills by wave IV, regardless of when the were adopted.
