NO.
Assuming a homogenous gaseous medium, the concentration of gas molecules will be evenly distributed and any movement against them in any direction produces the same change in pressure.
You aren't talking about changes in altitude, are you? Then the gaseous medium (air gets thinner as you ascend, and pressure changes decrease as you go up.
Specify the conditions better.

Ms. Chicago Fan...
Vertically. Near surface atmospheric changes equal about 28 to 32 feet per millibar/hectopascal, with that value increasing rapidly as you ascend through the atmosphere.
That is of course, in a standard atmospheric pressure of 1013.2mb

Vertically. If you move say 1 km horizontally or 1 km vertically, you will know the difference is much higher for the vertical movement. Hill stations are examples.

Vertically of course. When you reach 15,000' half of the atmosphere is below you in density/pressure.
