If it were only that easy... but the rational number have density 0 on any real interval (almost all real numbers are irrational), so any subset of the rationals is as well.

Allow me to jump out here and clearly display my ignorance: how about something like the set of rational numbers in lowest terms whose numerators (or denominators) are odd (or even)?

Can someone give me an example of a set of density 1/2 on every interval of the real numbers?
