It all depends! The only 'real' MPG is the one you are getting.
As I understand it, all those EPA estimates are done in a lab, and are
based on exhaust carbon mass and other data. Apparently their modelling
is not always so accurate.... EPA says 22/27 for me, I'm getting
32+/35+. I must drive like my dead-and-buried granny; all my vehicles
have exceeded EPA by a fair margin, even a guzzling Cherokee.
Freeway mileage is greatly dependent on speed. FWIW, my Accord ('92,
2.2L, 5-spd) gets 36~38 when tootling along two lane highways at 50~55,
but only 30~31 on the superslab at around 75. (These numbers don't
reflect many refils, so are ballpark only.) Your Civic, being smaller,
will probably be less sensitive to aero drag (compared with other
losses) and may have a faster 'sweet spot.' Still, most any vehicle
will do better when driven at somewhat reduced freeway speeds.
City driving is about anticipating red lights/stop signs and
gliding/coasting as much as is practical. Anytime you use the brake,
you are wasting gas, and dissipated energy goes up with the square of
the speed. If you forsee a stop ahead, gently ease off early, as much
as following traffic will tolerate. Braking to a stop from 40 wastes
nearly twice the energy as from 30.

Although EPA is alleged to overestimate mileage for many cars, for some
reason they sometimes underestimate it for Hondas (and Toyotas). EPA rated
my '93 Accord automatic at 28mpg on the highway, but I usually get 32-34mpg
under ideal conditions. In fact, I took a 450-mile road trip a couple
weekends ago and the car averaged 33mpg. I'm not an aggressive driver but
I'm not a slowpoke either; I usually drive 5-10 mph above the speed limit.
