Mibvunzo Yemuenzaniso Pakukurukurirana Kwehuwandu Hwevanhu
Pendauluan
Kuchinja kwevanhu ibazi rehuwandu hwevanhu rinoongorora shanduko nekufamba kwevanhu nekufamba kwenguva. Kuchinja uku kunogona kukonzerwa nezvinhu zvakasiyana-siyana, zvakaita sekuzvarwa, kufa, kutama kwevanhu, uye shanduko dzemagariro evanhu nehupfumi. Kunzwisisa kuchinjika kwevanhu kwakakosha pakuronga budiriro muzvikamu zvakasiyana-siyana, zvinosanganisira hutano, dzidzo, nehupfumi. Chinyorwa chino chichakurukura mienzaniso yakati wandei yemibvunzo nehurukuro dzine chekuita nekuchinjika kwevanhu.
Pfungwa Dzekutanga dzeMagariro Evanhu
Usati waenderera mberi nemibvunzo yemuenzaniso, zvakakosha kunzwisisa dzimwe pfungwa huru dzine chekuita nekuchinja kwehuwandu hwevanhu:
1. Kuzvarwa: Ichi ndicho chimwe chezvinhu zvikuru zvinokonzera kukura kwevanhu. Kuzvarwa kunogona kuonekwa kuburikidza nehuwandu hwekuzvarwa husina kunaka (CBR).
2. Rufu: Kusiyana nekuzvarwa, huwandu hwerufu hunokanganisa kudzikira kwehuwandu hwevanhu uye hunoyerwa nechiyero cherufu chisina kuchena (CDR).
3. Kutama: Kufamba kwevanhu kubva kune imwe nzvimbo kuenda kune imwe. Kutama kunogona kuitika mukati menyika imwe chete kana pasi rose (munyika dzakasiyana).
4. Kuwedzera Kwevanhu: Mugumisiro wemusiyano uripo pakati pekuzvarwa nekufa, pamwe nemusiyano uripo pakati pekutama kwevanhu vanoenda kune dzimwe nyika nekubva kune dzimwe nyika.
5. Kuvimba: Inoyera huwandu hwevanhu vasina kubereka (vari pasi pemakore 15 uye vanopfuura makore 64) nehuwandu hwevanhu vane makore ekuberekwa (makore 15-64).
Mibvunzo yemuenzaniso nekukurukurirana
Mubvunzo 1: Kuwedzera Kwehuwandu hwevanhu
Mubvunzo:
Kana nyika ine vanhu vanosvika mamiriyoni makumi mashanu pakutanga, vanhu vanozvarwa vasina kurongeka vanosvika makumi maviri nevashanu pavanhu chiuru pagore, uye vanhu vanofa vasina kurongeka vanosvika gumi pavanhu chiuru pagore, vanhu vanozove vakadini mushure megore rimwe chete kana pasina kutama?
Kukurukurirana:
1. Verenga huwandu hwekuzvarwa:
– CBR = 25 pavanhu 1000
– Huwandu hwevana vanozvarwa pagore = \( \frac{25}{1000} \kapetwa 50.000.000 = 1.250.000 \)
2. Verenga huwandu hwevakafa:
– CDR = 10 pavanhu 1000
– Huwandu hwevanhu vanofa pagore = \( \frac{10}{1000} \kapetwa 50.000.000 = 500.000 \)
3. Kukura kwevanhu pasina kutama:
– Kukura = Nhamba yekuzvarwa – Nhamba yevakafa
– Kukura = 1.250.000 – 500.000 = 750.000
4. Huwandu hwevanhu mushure megore rimwe chete:
– Huwandu hwevanhu hwekupedzisira = Huwandu hwevanhu vekutanga + Kukura
– Huwandu hwevanhu hwekupedzisira = 50.000.000 + 750.000 = 50.750.000
Saka, huwandu hwevanhu mushure megore rimwe chete hunosvika mamiriyoni makumi mashanu nemazana manomwe nemakumi mashanu ezviuru.
Mubvunzo 2: Kuvimba neVamwe
Mubvunzo:
Guta rine vanhu 30.000 vane makore ari pakati pe0-14, 70.000 vane makore ari pakati pe15-64, uye 20.000 vane makore 65 zvichikwira. Verenga huwandu hwevanhu vanovimba neguta.
Kukurukurirana:
1. Verenga huwandu hwevanhu vezera risingabereki:
– Vana (makore 0-14) = 30.000
– Vakwegura (makore 65+) = 20.000
– Huwandu = 30.000 + 20.000 = 50.000
2. Verenga chiyero chekuvimbika:
– Chiyero = \( \frac{\text{Nhamba yeVanhu Vasina Kubereka}}{\text{Nhamba yeVanhu Vezera Rinobereka}} \kawa 100 \)
– Chiyero = \( \frac{50.000}{70.000} \kawa 100 \inenge 71.43 \)
Saka, chiyero chevanhu vanovimba neguta iri chiri pa71,43. Izvi zvinoreva kuti pane vanhu vanovimbwa neguta vanenge 71 pavanhu zana vezera rekushanda.
Mubvunzo 3: Mhedzisiro yeKutama
Mubvunzo:
Nyika inowana huwandu hwevanhu kuburikidza nekutama kwevanhu vanosvika 200.000 uye kutama kwevanhu vanosvika 150.000 mugore rimwe chete. Kana kukura kwevanhu munyika (musiyano uripo pakati pekuzvarwa nekufa) kuri vanhu 500.000, huwandu hwevanhu munyika hunosvika papi?
Kukurukurirana:
1. Verenga musiyano wekufamba:
– Musiyano wekutama = Kutama-kuenda-kunze
– Musiyano wekufamba = 200.000 – 150.000 = 50.000
2. Verenga huwandu hwevanhu:
– Kukura kwese = Kukura kwechisikigo + Musiyano wekufamba
– Kukura kwese = 500.000 + 50.000 = 550.000
Saka, huwandu hwevanhu munyika yese hunosvika 550.000.
Mubvunzo 4: Kufungidzira Huwandu hwevanhu
Mubvunzo:
Kana huwandu hwevanhu huri kukura pagore hwenzvimbo imwe chete huri 2%, huwandu hwevanhu hunofungidzirwa kuti huchava hwakaita sei mumakore mashanu anotevera kana huwandu hwevanhu varipo parizvino huri vanhu zviuru zana?
Kukurukurirana:
1. Shandisa fomura yekufungidzira huwandu hwevanhu:
– \( P_t = P_0 (1 + r)^t \)
– \( P_t \) = fungidziro yevanhu mumakore t
– \( P_0 \) = huwandu hwevanhu huripo parizvino
– \(r \) = mwero wekukura kwegore negore
– \(t \) = nhamba yemakore
2. Isa kukosha mufomura:
– \( P_t = 100.000 (1 + 0.02)^5 \)
– \( P_t = 100.000 \nguva (1.02)^5 \)
– \( P_t \inenge 100.000 \kawa 1.10408 \)
– \( P_t \inenge 110.408 \)
Saka, huwandu hwevanhu hunofungidzirwa mumakore mashanu anotevera hunosvika vanhu vanosvika 110.408.
Mhedziso
Kuchinja kwehuwandu hwevanhu kunoita basa rakakosha mukuronga nekushandisa mutemo weveruzhinji. Kuburikidza nekunzwisisa kwakakodzera uye kuongorora pfungwa dzevanhu nedata, hurumende nemasangano akakodzera vanogona kugadzira nzira dzinoshanda dzekugadzirisa nyaya dzemagariro evanhu, hupfumi, uye zvakatipoteredza dzine chekuita nekushanduka kwehuwandu hwevanhu. Nekugadzirisa nekudzidza matambudziko emuenzaniso, tinogona kuwana kunzwisisa kwakajeka kwekuti kuchinja kwehuwandu hwevanhu kunokanganisa sei hupenyu hwezuva nezuva uye remangwana renharaunda.
