The detail that would be the LEAST likely to be included in a problem statement about a fundraising project proposed by a community group is the year the group was founded.
A problem statement typically focuses on the issues at hand, the goals of the fundraising, and the specifics regarding the fundraising effort itself, rather than the history of the organization. The other details—what the money will be used for, how long the group has to raise the money, and the amount of money needing to be raised—are more directly relevant to the fundraising project itself.
