Instead of zip use the following?

Use Addresses Use Census Units Use your own Spatial Index

Why not lat, long?

>>nancyp+s8
It depends on if you want to model a point or an area. lat/lng gives you a point, but you often want an area to, for example, count how many people are in that area. A spatial index like H3 provides a grid of area units.

But so do lat long ranges.
