Notice the differences in the times of sunrise on Jan 1 and Jan 31 and then note the differences between the times of sunsets on those same dates. Why do not the days grow longer equally at both sunrise & sunset?

you already said it "the days are growing longer" lol!
anyway, the suns path in the sky is becoming more and more elongated because the earths tilt is changing more towards the sun in the northern hemisphere. By June we will be tilted at max.

The time by the Sun varies by plus and minus 12 mins through the year because our orbit is an Ellipse. This variation happens faster than the rate of change of inclination of the Earths axis at the Solstices. Notice the average of your two days is very close to the solstice date.

The more north you go, the longer the sun stays up in the summer and it's the opposite in the winter. But this happens at the poles only!

I think it has to do with the latitude we're at. The spring and fall equinoxes are of equal length at the equator. Because of the axis of the earth, 23.5 degrees, we are never full on to the sun? I'm not a scientist but this is my theory..
