据财经调研机构SmartAsset公布最新的指标，在芝加哥，如果你的年收入在4.5万美元至13.3万美元之间就算中产阶级。在伊利诺伊州，年收入4.8万至$14.4万之间算中产阶级。
纽约、洛杉矶、芝加哥、休斯顿这四大城市的中产阶级收入的范围差别不大，与全美中产范围（3万-9万美元）相差也不算很大。
不过，硅谷所在地的加州湾区，年薪不到8万美元不算中产，年薪31万还是中产。
中产阶级的年收入界定也会因为庭成员数量、不同城市的消费水平而出现变化。
SmartAsset公布“2023全美大城市中产阶级收入”研究报告
SmartAsset对全美100个大城市、全美50州的中产阶级最新收入资料进行了统计分析，并公布“2023全美大城市中产阶级收入”研究报告。这项调研援引2021美国人口普查局的“美国社区调研报告”的资料，使用皮尤研究中心（PEW Resarch）对中产阶级的定义，即美国居民年薪中位数的67%到200%。
全美四大城市
中产水平相差不大
根据该报告，纽约、洛杉矶、芝加哥、休斯顿这四大城市的中产阶级收入水平相差不大。
美国四大城市中产阶级收入范围如下：
纽约市：$45,558 - $135,994
洛杉矶：$47,149 - $140,744
芝加哥：$44,606 - $133,152
休斯顿：$37,184 - $110,998
（均为个人年收入）
这四大城市的中产收入水平，相对而言也贴近全美中产收入水平（个人年收入3万至9万美元）。
加州湾区
8万年薪不算中产，31万还是中产
加州湾区（The Bay Area）是加州北部的海湾区域，主要包括三藩市(San Francisco)、圣何塞(San Jose)、弗瑞蒙(Fremont)等城市。作为硅谷所在地，湾区高科技公司云集，职工年薪高，不过当地消费水平，特别是房价也高。
加州湾区主要包括三藩市、圣何塞、弗瑞蒙
全美中产阶级门槛最高的前15大城市
在湾区，年薪8.2万是中产阶级的最低门槛，年薪高达25万乃至31万，还算中产阶级。
在全美中产阶级门槛最高的城市前五名，三都是加州湾区城市。其中弗瑞蒙（Fremont）位居全美最高，该市居民家庭年收入的中位数约15.6万，中产阶级的最低年收入为$104,499，中产最高上限为$311,936。
中西部城市
中产门槛普遍较低
在全美前100大城市中，中产阶级门槛最低的是俄亥俄州的克利夫兰市（Cleveland, OH），个人年收入超过$23,827即可跻身中产。看起来克利夫兰是全美“性价比”最高的城市。
美国中产阶级门槛最低的20个城市
在中产阶级门槛最低的全美十大城市中，中西部地区占据半壁江山，除了克利夫兰外，还包括底特律（Detroit,MI），辛辛那提（Cincinnati, OH），托来多（Toledo, OH），密沃基（Milwaukee, WI）。
全美50州
东海岸最高，南部最低
以州为单位统计，东海岸地区的中产门槛最高。全美中产阶级收入门槛最高的前五名，全部位于东北海岸，分别为：马里兰州、华盛顿特区、麻省、新泽西、新汉姆夏尔（New Hampshire）。在这前五名州，年收入得6万美元才算中产。
全美各州中产阶级收入门槛对比，颜色越深
在中产门槛最低五个州，四个位于南部，分别为密西西比、路易斯安那、阿肯色、阿拉巴马州。其中，密西西比州全美门槛最低，年收入达到$32,640即可步入中产阶级。
伊利诺伊州的中产阶级收入范围为（最低$48,377，最高$144,410）在全美属于偏高范围。
何为中产阶级？
不同科研机构对中产阶级有着不同的定义。皮尤研究中心（Pew Research Center）对中产的定义为全美居民收入中位数的67%到200%。
布鲁金斯学院（Brookings Institution）的定义为：美国居民收入20%至80%。Urban Institute的定义则为联邦贫困线的150%至500%。
SmartAsset公布的“2023全美大城市中产阶级收入”研究报告，是以皮尤中心的定义为准，为个人年收入。如果考虑家庭成员，中产门槛会相应升高。
全美范围的中产阶级收入范围
即使调整了生活成本差异后，东北部地区的工资仍然比南部地区高出20%左右。排名靠前的东北部各州生活成本比排名靠后的南部各州高出约50%，但中产阶级的资薪水平高出约70%。
纽约NYC的中产阶级收入跟不上生活成本。虽然旧金山和西雅图等城市的生活成本与中产阶级收入密切相关，但纽约客的工资水平却落后了；纽约市的工资水平在调查的城市中处于中等水平，但皇后区、布鲁克林和曼哈顿的成活成本分别比全美平均水平高出43%、70%和138%。
科技城市的中产阶级门槛最高。中产阶级收入门槛最高的前五名城市中，有三个位于加州旧金山湾区。
在这个加州城市年薪31万美元，依然属于中产。按统计标准来说，在加州Fremont年收入$311,936仍被视为中产，这是研究中所有城市的中产天花板，当地的家庭收入中位数比第二高城市高出近$30,000。这座湾区城市拥有近23万居民，其中近十分之一在特斯拉工作。
