There is no enough information on their numbers. Presumably the standards to be considered for ‘education or exhibition use’ are stringent and hard to meet considering there are thousands of USDA-licensed facilities that would love to obtain jerboas if it were possible.

Some Species of Jerboa that have been kept as Pets (some species are rare or impossible to find): Jerboas can jump up to a meter when they need to, and they rarely drink water, getting most of their hydration needs from the diet that they eat, although some species may lick morning dew [2]. - Pygmy Jerboa as a Pet - Exotic Pets at BellaOnline It has longer hind legs and shorter front legs. European jerboa owners have made a lot of progress since the small rodents went extinct in the United States pet trade.
The tail is longer than the body (up to 6 inches). Sometimes breeding success can help guide keepers towards conditions that may favor the welfare of captive animals. As jerboas cover a lot of area in their movements, excessive cage furniture is likely to offer less benefits than it would for other small pets. Lesser jerboas have a lifespan of about 5-6 years in captivity [3]. A pygmy jerboa, the smallest rodent in the world, and a highly desired exotic pet. Cooper, Kimberly L.

The Harvard breeding program, used corn cob bedding, but bedding acceptable for other small rodents, such as aspen, may work. This ban was lifted in 2008, but by then, the remaining jerboas in the United States had not bred well enough to sustain a captive population.
