Sounds a little low, but yup jeeps is thirsty critters!
Some (cheap) fuel economy tips that may help...

-Keep your tires at the correct pressure and keep your wheels alligned
(You wouldn't believe how much impact this has on your gas mileage)
-Blow out your air filter with some compressed air (or replace it).
-Pull your spark plugs and check them, replace if necessary. Make
sure you have a torque wrench to put them back 'cause you REALLY don't
want to over tighten them.
-In many jeep models the A/C compressor is running anytime you have it
set to "defrost" when the temp is above freezing. I don't know if
your model does this but if it does you can be killing your city gas
mileage without realizing it.
-Check the tension of your serpentine belt. Too tight can affect
mileage and also cause a lot of unnecessary wear and tear.
-Check your engine thermostat. If the engine is running too cold it
can also do a job on your gas mileage.
-Have you ever changed the tranny fluid (and the transfer case fluid)?
If not you are LONG overdue.
-Check the fluid in the front and rear diffs too while you are under
there just to be complete <grin>.

Is your jeep stock?
What type of foot do you have......? for example it takes 90% more gas
to go from 0 - 20 mph then from 20 - 50 mph.

First look to make sure you jeep is tuned up. Then start to look at how
you drive. I have a heavy foot and can see a huge change when use a
light foot.

the most you will get is 15 in the city

Jeep = Jest Empty Every Pocket

the other question is why do you have a jeep for the city?

Make sure there is no air leaks in the PVC hoses, etc.
I've a 89 with the PVC built into the value cover. I had
major leaks, when fixed, gas mileage improved 10%.

Depends on how heavy your foot hits the gas pedal. 

1. Tape a raw egg between your foot and the gas pedal.

2. Use a quad hook and rope, hitch a ride from the passing BMW.

Tires could be a big thing - I switched mine on my '88 from the off-roaders
it came with to car tires (the bare minimum in the owners manual) and got
4mgp back.

With the 4.0L, I'm getting 16mgp city, 22mgp highway.
