METHODOLOGY NOTES (across all datasets for this indicator)
List rents data reflects median rent prices advertised for available apartments rather than median rent payments; more information is available in the indicator definition above. Regional and local geographies rely on data collected by real Answers, a research organization and database publisher specializing in the multifamily housing market. real Answers focuses on collecting longitudinal data for individual rental properties through quarterly surveys. For the Bay Area, their database is comprised of properties with 40 to 3,000+ housing units. Median list prices most likely have an upward bias due to the exclusion of smaller properties. The bias may be most extreme in geographies where large rental properties represent a small portion of the overall rental market. A map of the individual properties surveyed is included in the Local Focus section.

Individual properties surveyed provided lower- and upper-bound ranges for the various types of housing available (studio, 1 bedroom, 2 bedroom, etc.). Median lower- and upper-bound prices are determined across all housing types for the regional and county geographies. The median list price represented in Vital Signs is the average of the median lower- and upper-bound prices for the region and counties. Median upper-bound prices are determined across all housing types for the city geographies. The median list price represented in Vital Signs is the median upper-bound price for cities. For simplicity, only the mean list rent is displayed for the individual properties. The metro areas geography rely upon Zillow data, which is the median price for rentals listed through www.zillow.com during the month. Like the real Answers data, Zillow's median list prices most likely have an upward bias since small properties are underrepresented in Zillow's listings. The metro area data for the Bay Area cannot be compared to the regional Bay Area data. Due to afore mentioned data limitations, this data is suitable for analyzing the change in list rents over time but not necessarily comparisons of absolute list rents. Metro area boundaries reflects today’s metro area definitions by county for consistency, rather than historical metro area boundaries.

Due to the limited number of rental properties surveyed, city-level data is unavailable for Atherton, Belvedere, Brisbane, Calistoga, Clayton, Cloverdale, Cotati, Fairfax, Half Moon Bay, Healdsburg, Hillsborough, Los Altos Hills, Monte Sereno, Moranga, Oakley, Orinda, Portola Valley, Rio Vista, Ross, San Anselmo, San Carlos, Saratoga, Sebastopol, Windsor, Woodside, and Yountville.

Inflation-adjusted data are presented to illustrate how rents have grown relative to overall price increases; that said, the use of the Consumer Price Index does create some challenges given the fact that housing represents a major chunk of consumer goods bundle used to calculate CPI. This reflects a methodological tradeoff between precision and accuracy and is a common concern when working with any commodity that is a major component of CPI itself. Percent change in inflation-adjusted median is calculated with respect to the median price from the fourth quarter or December of the base year.

方法论说明（适用于该指标的所有数据集）
租赁价格数据反映了可供出租公寓的广告中位数租金，而非中位数租金支付；更详细的信息请参阅上述指标定义。区域和地方地理区域依赖于专门从事多户型住房市场研究和数据库出版的机构real Answers收集的数据。real Answers专注于通过季度调查收集单个租赁财产的纵向数据。对于旧金山湾区，其数据库包括40至3,000多个住宅单位的财产。中位数列表价格可能存在向上偏差，因为小型财产被排除在外。在大型租赁财产在整体租赁市场中占比较小的地理区域，这种偏差可能最为显著。所调查的个别财产的地图包含在地方焦点部分。

所调查的个别财产提供了各种类型住房（如单室、一室一厅、两室等）的下限和上限价格范围。对于区域和县级地理区域，所有住房类型的中位数下限和上限价格被确定。Vital Signs中代表的中位数列表价格是区域和县的中位数下限和上限价格的平均值。对于城市地理区域，中位数上限价格是所有住房类型的中位数上限价格。为了简化，仅显示个别财产的平均列表租金。大都市地理区域依赖于Zillow数据，这是www.zillow.com上在该月发布的租赁的中位数价格。与real Answers数据一样，Zillow的中位数列表价格可能存在向上偏差，因为小型财产在Zillow的列表中代表性不足。由于上述数据限制，这些数据适合于分析列表租金随时间的变化，但并不一定适用于绝对列表租金的比较。大都市边界反映了今天的县定义的大都市边界，以确保一致性，而不是历史的大都市边界。

由于调查的租赁财产数量有限，以下城市的市级数据不可用：Atherton、Belvedere、Brisbane、Calistoga、Clayton、Cloverdale、Cotati、Fairfax、Half Moon Bay、Healdsburg、Hillsborough、Los Altos Hills、Monte Sereno、Moraga、Oakley、Orinda、Portola Valley、Rio Vista、Ross、San Anselmo、San Carlos、Saratoga、Sebastopol、Windsor、Woodside和Yountville。

通货膨胀调整后的数据被用来展示租金相对于总体价格增长的情况；然而，使用消费者价格指数确实存在一些挑战，因为住房是用于计算CPI的消费者商品组合中的主要部分。这反映了精度与准确之间的方法论权衡，并且在处理任何自身即为CPI主要组成部分的商品时，这是一个常见的担忧。通货膨胀调整后的中位数百分比变化是根据基准年度第四季度或十二月的平均价格计算的。
