Ideal Density

I think a lot of urbanites probably assume that more density is usually better, but I have a feeling that there is an optimal amount density. That optimal density level would balance walkability, housing prices, environmental benefits, and similar factors, but balances with the negative affects of density, like the feelings of crowdedness and noise, access to nature, views, and access to sunlight. Of course, this ignores styles of density, where perhaps you can skew the results one way or another depending on the style of development — you may be able to have more nature sprinkled throughout a “towers in the park” style of development, but that may affect access to sunlight and obstruct views, so perhaps an optimal density would still apply.
