I love to see metrics that evolve over time. Land is a finite resources, as such it inevitably trends up as the best and easiest locations are consumed. So I think the correlation here has to be understood from that baseline.
Land as a finite resource only affects first tier real estate market markets. You can see this vividly in China where there's a housing glut on aggregate, but not in first tier cities.
That's too simplistic. The best (and maybe even easiest) locations and local population evolve over time as well. Land can be developed in different ways, allowing for different density. Different people buy property for different reasons, which affects its value.
Land is finite but not meaningfully so at this point. If my early morning napkin math is right, we could give every person on earth about 6.4 acres of land.
Land where people want to live is scarce. Obviously a variety of factors but one of them is that land is bifurcating the way income is. Small amounts are growing in value rapidly and the rest is declining (or growing more slowly). Urban property is skyrocketing, rural property in coal country is struggling.
