Reporting Segments [Abstract]
Reporting Segments	2. Reporting Segments Our homebuilding operations are engaged in the development, design, construction, marketing and sale of single-family attached and detached homes in 17 states. We build and sell homes under our Century Communities and Century Complete brands. Our Century Communities brand is managed by geographic location, and each of our four geographic regions offers a wide range of buyer profiles including: entry-level, first and second time move-up, and lifestyle homebuyers, and provides our homebuyers with the ability to personalize their homes through certain option and upgrade selections. Each of our four geographic regions is considered a separate operating segment. Our Century Complete brand targets entry-level homebuyers, primarily sells homes through retail studios and the internet, and generally provides no option or upgrade selections. Our Century Complete brand currently has operations in 11 states and is managed separately from our four geographic regions. Accordingly, it is considered a separate operating segment.The management of our four Century Communities geographic regions and Century Complete reports to our chief operating decision makers (which we refer to as “CODMs”), the Co-Chief Executive Officers of our Company. The CODMs review the results of our operations, including total revenue and income before income tax expense to determine profitability and to allocate resources. Accordingly, we have presented our homebuilding operations as the following five reportable segments: West (California and Washington)Mountain (Arizona, Colorado, Nevada and Utah) Texas Southeast (Florida, Georgia, North Carolina, South Carolina and Tennessee)Century Complete (Alabama, Arizona, Florida, Georgia, Indiana, Kentucky, Michigan, North Carolina, Ohio, South Carolina and Texas) We have also identified our Financial Services operations, which provide mortgage, title, and insurance services to our homebuyers, as a sixth reportable segment. Our Corporate operations are a non-operating segment, as it serves to support our homebuilding, and to a lesser extent our Financial Services operations, through functions, such as our executive, finance, treasury, human resources, accounting and legal departments.  The following table summarizes total revenue and income before income tax expense by segment (in thousands): Year Ended December 31, 2021 2020 2019Revenue: West$ 1,022,523 $ 683,138 $ 534,613Mountain 1,151,911 860,041 729,045Texas 481,915 339,346 252,921Southeast 663,728 672,790 548,661Century Complete 772,499 502,569 427,409Financial Services 123,738 103,308 43,262Corporate — — —Total revenue$ 4,216,314 $ 3,161,192 $ 2,535,911 Income (loss) before income tax expense: West$ 213,301 $ 71,417 $ 43,027Mountain 212,335 114,722 89,201Texas 68,565 34,694 25,866Southeast 92,420 57,181 31,435Century Complete 109,213 33,449 22,044Financial Services 51,160 48,511 10,687Corporate (105,872) (89,734) (89,625)Total income before income tax expense $ 641,122 $ 270,240 $ 132,635 The following table summarizes total assets by segment (in thousands): December 31, December 31, 2021 2020West $ 668,830 $ 536,907Mountain 1,008,481 778,198Texas 322,302 207,746Southeast 360,644 329,930Century Complete 371,096 218,604Financial Services 533,159 421,153Corporate 232,364 352,555Total assets $ 3,496,876 $ 2,845,093Corporate assets include certain cash and cash equivalents, certain property and equipment, prepaid insurance, and deferred financing costs on our revolving line of credit.
