I was going off memory and I used 1.5% b/c I thought the actual rate was something like 1.2% or 1.3%.

A 1% growth rate is basically a rounding error. A nothing.
Where the intelligence factor comes in is when someone doesn’t like or understand that 1.1% is a nothing burger they start going on about “LA Basin’s worth of people” as if that somehow changes the argument. Smart people understand percentages. Dumb people think “well golly that’s a lot of people”.

It’s 1% of what we already have.

For some context the LA Basin size wise is about 5k square miles. The US as a country is close to 4m square miles. (Yes, I looked up both but feel free to check them). And we’re talking a worldwide growth rate.
