High correlation would indicate investment in preventative and supportive services, while variable, is approximately aligned across all ethnic groups. These relatively low correlations suggest that many local authorities have services that are associated with rates of children in care in very different ways depending on the ethnicity of the child population. ] .pull-right[ .center[ <img src="ipse-final-pres-full_files/figure-html/unnamed-chunk-42-1.png" width="550" height="500" style="display: block; margin: auto;" /> ] ] --- class: middle .middle-left-small[ <br> ### Despite the fact that we might expect the relationship between spending and rates of care to be stronger in urban local authorities, this did not seem to be the case. The relationship was broadly similar across local authorities in urban, rural, and rural with significant urban regions, with the relationship implying slightly more effectiveness in areas with at least some rurality. This may reflect differences in access to or the capacity of services, or the way experiences of poverty differ in ways where services may be more effective than cash transfers. ] .pull-right-big[ <img src="ipse-final-pres-full_files/figure-html/unnamed-chunk-43-1.png" width="650" height="500" /> ] --- class: inverse, middle .middle-left-big[ <br> # .white[I.VI Findings:] Investing in Prevention .white[&] Support: Summary ] .pull-right-small[ <img src="images/geometric-flower.svg" width="80%" style="display: block; margin: auto;" /> ] --- class: inverse, middle .middle-left-big[ <br> ## There was strong evidence to support the idea that investing in prevention and support effectively reduces rates of child welfare interventions, specifically, rates of children in care or on child protection plans. ] .pull-right-small[ <img src="images/geometric-flower.svg" width="80%" style="display: block; margin: auto;" /> ] --- class: inverse, middle .middle-left-big[ <br> ## Reduced spending on preventative and supportive services can explain a substantial proportion of recent increased in rates of children in care, but increases in child poverty have been more impactful.
