None. You compare current poverty rates to historical poverty rates and factor in the introduction of government programs as well as measures to keep people from entering poverty and you have yourself a pretty good indicator of whether the war on poverty has been successful. The US as a country has achieved a level of wealth that can't even be understood by people in 3rd world countries. Even the poorest Americans can count on dozens of government programs to help them, as well as hundreds of charities to pick up the slack. Whether Americans use them effectively or not is up to them but we certainly aren't facing starvation or poverty like the kind seen by our southern neighbors. FFS, we live in a country where the poverty line is set at $23K! There are entire families in Pakistan living comfortably on a 4th of that! So yeah, none of those even measure the success or failure of the "war on poverty" because the US' war on poverty is a bit of a joke to begin with.
