调查显示:83.2%的被调查居民对家庭幸福
感标准化评分超过6分,41.9%的家庭超过7分,全国平均水平为6.90分,这意味着大多数家庭感觉幸福。

style="TEXT-INDENT: 2em">调查结果同时显示:我国城乡居民之间、不同人群之间的家庭幸福感存在明显差异,在经济社会发展和人口
转变中体现出更多的复杂性、多样性。
比如,城镇居民感觉幸福的家庭比例为82.4%,这一比例在农
村为83.8%,稍高于城镇。
家庭幸福感较高的人群特征明显,主要为“老年、女性、初婚、受教育程
度较高、家庭经济状况良好、家庭和邻里关系良好”。
农民工、留守妇女、留守儿童、空巢家庭等群
体家庭幸福感普遍偏低,应给予更多关注。

的机会。至少在这一刻,可以静下心来,看一看、想一想,家庭幸福对我们每个人到底意味着什么。
2em">心态至上:40后进入幸福感收获期
人生漫漫,难免波折。是初入社会的年轻
人家庭更幸福,还是经历坎坷的老年人幸福感更高呢?此次调查显示:40后家庭幸福感最高,为7.06分,50后为7.02分,80后为6.83分,
90后的家庭幸福感最低,为6.68分,呈现出家庭幸福感随年龄递增的特点。这意味着,40后、50后正处于家庭幸福感的收获期。
style="TEXT-INDENT: 2em">北京大学社会学系教授李建新说,人的年纪越大,对家庭投入得越多,从中得到的满足感越高;而80后、90
后群体正面临就业、购房等巨大压力,对幸福的定义和感受也不尽相同。
40后、50后群体组成家庭的
时间更长,他们更多地体会到了与婚姻相伴随的生育及子女抚养过程,从中获得了更多积极的情感体验。同时,较高的家庭幸福感也同40
后处于生命周期的最后阶段相关。相对丰厚的社会经济资源,丰富的人生阅历,以及他们成长年代的集体主义社会价值观的濡染,让他们
的心态更加豁达,能够运用更加平和的心态看待自己的处境,对情感的控制能力更强,不会像中青年群体那样抱有过多的期望和追求。中
国人民大学社会与人口学院教授杜鹏说,在回答“认为对家庭幸福感有影响的因素”这一问题时,老年人只有一项的比例超过其他年龄人
群,那就是心态好(分别为52%和39%)。
如今,40后、50后群体大多已经离退休,他们不再像身处职场
的人们一样面临着升职、加薪的压力。从工作岗位上退下来后,他们有了更多的闲暇时间投身于自己的爱好,可以更多地享受家庭生活,
因而主观满意度高,家庭幸福感体验也更为强烈。
相比之下,80后、90后群体刚刚从校园走向工作岗
