Definitions of homelessness
The federal government has several definitions of homelessness, with varying criteria for being considered “homeless,” as summarized in the table below. For example, if a family is living out of their car, they would be considered homeless under both the US Department of Housing and Urban Development (HUD) and US Department of Education (ED) definitions. However, if a family lost their home and is forced to share housing with someone else, ED would consider the children to be homeless, but HUD would not.

Official counts of homelessness
Because there are varying definitions of homelessness, there are varying counts, each with certain limitations.
 The Delaware Continuum of Care, a statewide planning group, publishes an annual count of people in emergency shelters or transitional housing (2,357 people in 2016). However, it doesn’t include those living in unsheltered locations or doubledup.
 Housing Alliance Delaware conducts Delaware’s annual pointintime count, a onenight count of everyone considered homeless under the HUD definition (1,082 on January 31, 2018). However, this doesn’t include those who are doubledup, and is only a snapshot — not an annual total.
 All school districts collect and submit information about students experiencing homelessness to the federal Department of Education (3,227 in Delaware in the 20152016 school year). However, this doesn’t include children under age 3 or nonstudents.

Number of children experiencing homelessness in Delaware
Due to these limitations, the National Center on Family Homelessness has established a methodology for estimating the number of children experiencing homelessness. It uses the US Department of Education data, because it is “the only dataset that comprehensively assesses the number of homeless children by state … public schools are the only institutions legally responsible for identifying and serving children experiencing homelessness.” This methodology is also used by the Administration for Children and Families at the US Department of Health and Human Services and cited by Family Promise® nationally. Figures may be rounded.
 “[Subtract] the number of homeless children ages 3 to 5 who were enrolled in public school from the total number of homeless children enrolled in each state to find the K12 total.”

3,227 (total number of homeless children) – 30 (total ages 35) = 3,197

“Because the most current research estimates that 51% of the total number of homeless children are under the age of 6 (Samuels, Shinn & Buckner, 2010; HUD, 2009), the ED count of K12 homeless children [i.e., the number from Step 1] represents 49% of the total number of homeless children. … [Use] a ratio to calculate the total number of homeless children in each state … number of K12 homeless children x 100 / 49 = total number of homeless children.”
 3,197 x 100/49.2 = 6,498 estimated children experiencing homelessness annually

To determine the ratio of children experiencing homelessness (1 in N), the latest Census data is used.
 204,439 children in Delaware / 6,498 experiencing homelessness = 31.5 (1 in 31.5 children experience homelessness)

To determine the average rate of children experiencing homelessness per day, the total estimated number of children experiencing homelessness per year is divided by 365 (days per year).

6,498 ÷ 365 = 17.8 children becoming homeless per day, on average

To determine how often per day, on average, a child becomes homeless, the average daily rate is divided by 24 (hours per day), to determine an average hourly rate. The inverse of that hourly rate is then calculated and converted to minutes by multiplying by 60 (minutes per hour).
 17.8 ÷ 24 = 0.74 children becoming homeless per hour, on average
 1 ÷ 0.74 = 1 child becoming homeless every 1.38 hours
 1.38 x 60 = 1 child becoming homeless every 80.8 minutes
Cost of child homelessness
People’s Emergency Center, a homelessness service and advocacy organization in Philadelphia, has created a methodology for estimating the annual cost of child homelessness. Based on 13 cost categories, this methodology calculates the total marginal cost, defined as the “additional cost of serving children who have experienced homelessness above and beyond the cost associated with addressing the needs of children who have not experienced homelessness.”
Housing affordability in Delaware
The National Low Income Housing Coalition has developed a methodology for determining housing affordability, as follows:

First, the state’s Fair Market Rent must be calculated. HUD determines Fair Market Rents (FMRs) for metropolitan areas. To determine the FMR for a state, NLIHC calculates a weighted average of county’s FMR. “The weight for FMRs is the number of renter households within each county from the fiveyear 20122016 ACS.”
 In Delaware, using HUD’s Fiscal Year 2019 FMRs (effective as of Oct. 1, 2018) for 2bedroom apartments, the statewide weighted average is $1,142.

For housing to be “affordable,” according to longstanding federal policy, it must require spending “no more than 30% of a household’s gross income” on “gross housing costs.” To calculate needed yearly wages for housing to be affordable, multiply the statewide FMR by 12 (months), then divide by 0.3.
 $1,142 x 12 ÷ 0.3 = $45,668 needed per year to afford a 2bedroom apartment at the statewide Delaware FMR.

A fulltime job is defined as working 40 hours/week and 52 weeks/year, or 2,080 hours/year. Thus, total wages/year at minimum wage is 2,080 multiplied by the state’s minimum wage. To calculate the number of minimumwage jobs needed to afford housing, divide the amount from the previous step by the total wages/year.
 In Delaware, minimum wage is $8.25/hour. A fulltime job would earn $17,160/year. $45,668 ÷ $17,160 = 2.7 fulltime minimum wage jobs.

To calculate the number of hours per week needed to afford housing, multiply the number of fulltime minimumwage jobs by 40 hours/week.
 2.7 x 40 = 106 hours/week
Homeless voters
In Delaware, individuals without a “fixed address” can still register to vote by using the address of a “shelter, agency or another location where [they] receive [their] mail.” This analysis starts with a list of voters in Delaware whose address is one of Delaware’s homeless shelters (n=501). That list is then analyzed to determine the proportion that voted in the last general election (n=95). Given the inherent variability of data regarding people experiencing the homelessness, this proportion (95 ÷ 501 = 19%) is rounded to the nearest factor of 10 (= 20%).
