There are many approaches to conceptualizing and measuring the well-being of children. These indices vary considerably depending on the goal of the scale. However, all of these indices share similar characteristics in that they are multi-dimensional and take into account the complexity of children’s lives. One of the best known of these measures is the Annie E. Casey Foundation’s national KIDS COUNT Data Book (http://www.aecf.org/resources/the-2016-kids-countdata-book/). Each year since 1990 the Casey Foundation has released the KIDS COUNT Data Book. This data provides key information about dimensions of child well-being in the following areas: health, education, economic well-being and family and community. During the past 10 years the KIDS COUNT project has provided a website that has data of more than 100 state level measures of child well-being, and also provides county level data for each state.
