Ummmm, statistics are actual numbers. Given that it's percentages, the population in 1964 was 191 million, so about 33.2 million people and 2014 (where the 14.5% came from; it's 15% in 2016) 318 million, so about 46.1 million. How do the actual numbers make your point? More people by absolute numbers are considered in poverty after spending over $22 trillion (2014).

False dichotomy: the only two choices aren't to spend $22 trillion or let people die in the gutters. Was the US a civilized society prior to 1964? Do you think the federal government is the most efficient method for helping the poor? Are they helping? We can totally eliminate poverty by going into massive debt and giving every person in the US a million dollars. Would that be smart? Why not? How do you define "in need"? Are you willing to go into personal debt to keep people out of the gutters? Why not? Is it justifiable to get the government to force that debt on everyone? Why is it different?
You really want to pick 1964?
Because the answer is clearly, fuck no, it wasn't civilized. For a whole host of reasons, nevermind Medicaid/Medicare, Social Security, etc.
And I asked for numbers, not statistics, because saying that the war on poverty has "only" helped reduce poverty by 3%, as if 3% doesn't equate to helping out MILLIONS of people and their families over the past 63 years.
Not to mention that when it helps people out, it goes to different people at different times, often helping lift people out of poverty permanently, while helping the newly impoverished, unless you want to pretend that it's only the same people who've been poor for the past 63 years.
Absolute numbers?
17.3% of 318 Million = 55 million people.
14.5% of 318 Million = 46 million people.
That means 9 million of your fellow citizens are not living under the poverty line right now, who might be had the programs not been in existence. That's right now. Never mind any one particular point in time over the past 63 years.
And that is just the "reduction" in people living under the poverty line, not taking into account how many millions of people are able to eat and live inside because of those programs. Just dismissing the programs as "only reducing", never mind the fact that they are meant to help people who are IN poverty.
22 Trillion / 63 Years = $350,000,000 per year. Which sounds like a lot until you remember what the GDP is. Which sounds like a lot until you remember how much is spent on bombs and bullets each year, acting as a job welfare program for companies like Boeing, Raytheon, etc.
And, of course, until you remember that the money that goes into helping people, gets spent DIRECTLY BACK INTO THE ECONOMY. It isn't put into offshore accounts, or given to Wall St. to inflate bubbles. It gets spent at local businesses, corporations, babysitters, etc. In other words, the money simply helps a few MILLION people out, before it goes Right. Back. Into. The. Economy.
But you're left with a giant strawman you carefully douse with napalm before smiling and lighting it ablaze. No one is talking about giving everyone a million dollars, or forcing anyone into debt. It's a government assistance program that can be funded and stewarded more or less, depending on whether the people in charge are competent, incompetent, or shitbags who don't care.
Until politicians and the electorate are able to grapple with the actual problems, instead of the symptoms, we have to treat the symptoms. Poverty is a symptom of corporate capitalism. Full stop.
