At this point, HHS is not estimating the number of children for which care may be needed in the coming year:
No decisions have been made regarding the need for surge capacity in 2015, but ORR is exploring options available should the need arise. The purpose of the temporary structures with staffing and services is to identify agencies capable of standing-up soft-sided structures, trailers, or other temporary structures that could shelter 100-2,500 children on federally leased or owned land.The Washington Post reported in October that homeland security chief Jeh Johnson placed the fiscal 2014 total of unaccompanied children at 68,434. After an enormous surge in the summer months, the numbers fell quickly in the fall. It is not yet clear if President Obama's immigration actions announced in late November have had any impact on that trend.
