CALCULATING LOCAL ALLOCATIONS
USING THE JABG FORMULA
Title I of the Omnibus Crime Control and Safe Streets Act., which describes the
JABG Program, requires that states allocate funds to localities based on a weighted
formula of juvenile justice expenditures and Part I violent crimes. The formula is
designed for states to distribute threefourths of the passthrough funds based on
expenditures, and onefourth based on crime.
To accomplish this split, the total amount of money the state intends to pass through
to localities is divided into two "pools": the expenditures pool (threefourths
of the total passthrough amount), and the crime pool (onefourth of the total
passthrough amount). Each pool is then divided among localities based on the percentage
of the total state expenditure and crime numbers that their locality represents. The two
pool allocations for each locality are then added together to arrive at the total
allocation.
Here is an example of how the local allocation is calculated:
Anystate will receive $800,000 in JABG funds. Assuming that Anystate passes through 75%
of its allocation to its localities, it will distribute $600,000. Assuming that there are
only five local governments in Anystate, the crime and expenditure data for the localities
are shown below:
Locality 
Number of Part I Crimes 
Justice Expenditures 
City 1 
20,000 
$6,000,000 
City 2 
10,000 
$3,000,000 
County 1 
15,000 
$5,000,000 
County 2 
4,800 
$990,000 
Town 1 
200 
$10,000 
Total State 
50,000 
$15,000,000 
Each of the above numbers is converted to a percentage by dividing it into the state total
shown in the bottom row of the table. The results are shown below:
Locality

Percent of Justice Expenditures 
City 1 
40.00%

The two pool amounts for the state are $450,000 based on justice expenditures
(threefourths of $600,000 total passthrough), and $150,000 based on Part I violent
crimes (onefourth of the $600,000). Funds in each pool are allocated to the localities
according to the percentages in the table above (for example, City 1 receives 40% of the
$150,000 crime pool and 40% of the $450,000 expenditure pool). The results of these
calculations are shown below. The total allocation for each locality shown in the last
column is found by adding together the allocations from the two pools.

Total State

The final allocations are as follows:
City 1 
$240,000 
City 2 
120,000 
County 1 
194,985 
County 2 
44,100 
Town 1 
0 
Since the allocation for Town 1 is less than $10,000, Town 1 receives no JABG funds.
